Tender juicy grilled flank steak stuffed with peppers, onions, and cheese. A wonder low carb steak fajita recipe you won’t want to miss. This post is sponsored by Saber.
I am wiggling in my chair with delight as I write this. Seriously, just kind of dancing with joy over here, albeit from a seated position with my computer on my lap. I am just so excited and my excitement comes from a number of sources. For one thing, it is finally nice here in Portland and seeing the sun and feeling a little warmth has done wonders for my overall mood. And for another thing, this low carb stuffed flank steak recipe is beyond amazing and you are going to want to rush out and get the ingredients for it. And for the last thing, I am sitting here knowing that one of YOU will win an amazing Saber Grill, so you can grill your heart out this summer. Can you dig it?
I do not own one of these grills but after getting a good look at it, I sure wish I did. I have a pretty good grill but it’s not this good and I am trying to come up with a reason to get this for myself. Memorial Day? Father’s Day? Fourth of July? Hey, wait…Canada’s 150th birthday is this year. Surely that’s a good reason to purchase myself a spectacular new grill? Now I just need to convince my husband…
In all seriousness, I am delighted to be working with Saber to bring you this fantastic giveaway. Grilled foods are practically my raison d’être. Seriously, in the good weather, I live to grill. I’ve even been known to brave the poor weather, if I am craving a good grilled steak. And Saber is one of the most respected names in the grilling biz. They have an advanced infrared cooking system that eliminates flare-ups and uses 30% less fuel than traditional gas grills. With fast, efficient, and even heat, you always get delicious, juicy results. No wonder their tagline is For the Love of Food. Which dovetails pretty well with the fact that I dream about food all day.
To give you ideas on how to use your new Saber grill, they asked me to come up with a creative steak recipe. I love a good grilled steak and often I just throw some salt and pepper on it and away we go. But there are always great ways to add flavour and this Fajita Stuffed Flank Steak was fun and delicious. And really not all that hard to make. One word of warning, though. The melty cheese begins to ooze out the ends toward the end of cooking. Plenty of it stays in the rolled steak but if you don’t want to see all that delicious stuff go to waste, I suggest you keep some tin foil nearby. Once you move the steak roll to indirect heat, you can put it on a piece of tin foil and catch all that melted pepper jack! I confess, I ate mine with a spoon right off the tin foil, before I sliced the steak!
The giveaway is over.
But you have to check out this great recipe for Chuck Eye Steaks from Wicked Spatula. She’s telling you how to make cheap chuck steak taste as good as ribeye! How awesome is that?

Tender juicy grilled flank steak stuffed with peppers, onions, and cheese. A wonder low carb steak fajita recipe you won’t want to miss.
- 2 tbsp avocado oil
- 1/2 green pepper thinly sliced
- 1/2 red pepper thinly sliced
- 1/2 orange pepper thinly sliced
- 1/2 onion thinly sliced
- 3 tbsp taco seasoning
- 1 1/2 pound flank steak butterflied
- Salt and pepper
- 4 ounces pepper jack cheese thinly sliced
-
Preheat the grill to medium high. If using a charcoal grill, prepare it for indirect heat.
-
In a large skillet, heat the oil over medium heat until shimmering. Add the peppers and onion and sauté until just tender, about 5 to 7 minutes. Add the taco seasoning and continue to cook another 2 minutes.
-
Lay the flank steak open like a book on a work surface. Sprinkle with salt and pepper. Arrange the peppers and onions over so that they are all lying with the grain of the meat. Leave about 2 inches at one end of the meat with no fillings on it (this helps when rolling it up). Arrange the slices of pepper jack cheese overtop of the peppers and onions.
-
Starting at the end that is well covered by fillings and working toward the uncovered end, roll the flank steak up tightly. Secure well with 5 or 6 pieces of kitchen twine. Sprinkle with more salt and pepper.
-
Place the roll on the grill over direct heat and brown on all sides, about 2 minutes per side. Then move the roll over indirect heat (if using a gas grill, turn off one element and set the roll over the this part). Place so that the seam of the roll is facing up (less cheese will leak out this way!)
-
Let the flank steak continue to cook over indirect heat until cooked to your liking. About 125F to 135F on an instant read thermometer for medium rare. If your cheese is melting and leaking out too much, place the roll on a large piece of tin foil and continue to cook.
-
Remove to a tray and tent with foil. Let rest 10 minutes. Slice and serve.

Love flank steak. Can’t wait to try this!
Dorrrie Cooper says
It looks absolutely scrumptious and fairly easy to put together, even during the week after work.
Bethany says
That steak looks amazing!
Jennifer says
I have a flank steak in my refrigerator and this looks much more fun than what I had planned for it…..now if I only had that grill to cook it on I would be all set!
Tracy says
This looks great! I would love to have that grill to cook this on…and just about everything else we eat this summer.
Ann McCann says
The recipe is simple and more appetizing than `hunk of meat on a plate’! We use charcoal rather than a cheap gas grill. This one..lusting!
Amanda says
Truthfully, I have never heard of Saber grills, but the photo looks like it is fantastic! I will have to do some research! The recipe, of course, looks scrumptious! Thanks for the chance to win!
Paula Smith says
Cannot wait to try this!
Tracy Cook says
I can’t wait to try this recipe, although I may need to substitute a different cut of meat. Flank steak is hard to find where I live.
Carolyn says
Any low flat cut will probably do. Make sure it’s cut quite thinly and/or pound it thin to about 1/2 inch.
Megan says
Looks delicious! Hoping I win My kids and I are getting my hubby a grill for Father’s Day. How awesome if we win! ?
Carolyn says
Awesome! I really want to get this grill. My old Weber is still going strong but…
Amber Evans says
This is a recipe that I would love to try as my husband loves fajitas but my hips do NOT love the tortilla wraps so this would be a great compromise!!!
Carolyn says
Exactly! You get the same great flavours this way, but very low carb!
Shelley says
Thank you for the recipe! Have a flank steak in the freezer with this recipes’ name on it!
Susan Jordan says
Would love to replace our old grill with this one.
Kath says
Your fajita stuffed flank steak is so creative! Thanks for the recipe.
Sara says
Looks delicious! And a super cool grill!
Linda says
The recipe looks super yummy.
The grill looks like one I’d love to have. I miss grilling my foods. I con’t even use my broiler because it sets off my smoke detector.
Rachelle says
I hope I can try this recipe on one of those awesome grills! We have been in need of a grill for some time now and hoping to get a nice one. Thanks for the giveaway and all of your amazing recipes!!
Michelle G. says
Yum. looks delicious!
Sharon says
This recipe has my husband and I drooling! And to win this grill for him for Father’s Day would be fantastic as he is the world’s BEST father and husband! I would know because we’ve been married for 52 years.
Rachelle says
52 yrs, that’s awesome! God bless you! Shalom ❤
Larry says
I like the recipe. I think I’ll make that, smoke it, and slice it. Then use it for making flats with 2 ingredient quinoa. Should be tasty.
Jen R says
I’m going to try this. I am always looking for easy, healthy recipes to cook for lunches!
Amanda says
This recipe looks delicious! I can’t wait to try it. I have never grilled, so I would be thrilled to win a Saber Grill

This Saber Grill looks totally awesome! I would imagine that I could entertain my entire family by having it available for get togethers!
Dannette says
The recipe looks wonderful and the grill looks fantastic. Flank steak is one of our favorites. Hoping we can test that recipe on that Saber grill!
Kathy E. says
The recipe looks and sounds fantastic, but I know I’ll have problems finding orange pepper. I will look, but may have to may it without. I want to buy a Saber Grill for my husband for Father’s Day…we need one!
Carolyn says
Use a whole red pepper instead of a half. 🙂 It’s just for colour.
Felicia H. says
This is one of my favorite kind of meals. Can’t wait to try this! I am looking for a new grill and this sounds really good.
grace says
well, i think both are pretty outstanding! i haven’t seen a flank steak recipe like this before. 🙂
Tory says
We often do quick ‘frying pan fajitas’, but with the coming of good weather, this is a super grill idea! Costco has lovely flank steaks, and since my grill is defunct I’ll get my son to cook on his!! 🙂
Carol says
I am dying to try this recipe. It looks amazing. Flank steak is my favorite meal so I’ll have to try this. The Saber grill looks amazing as well!

Sandy Munn says
That flank steak recipe looks so delicious! Our gas grill is pretty old. It would be nice to be able to replace it with a Saber grill. Even though we live in the middle of Nebraska, we grill a lot…..even on nicer days in the winter!
Alie says
Looks delicious! Grilling season down in Los Angeles has been going strong for a while now, so we will absolutely be checking this out!
jodi says
I am making this tonight but will sub a skirt steak since I don’t have anymore flanks. Not sure which I am drooling over more the recipe or the grill….I have a huge bag of mini sweet peppers and a pound of pepper jack cheese that I have been planning on using and this fills the ticket! Thanks for the recipe!
Carolyn says
Sounds perfect!
Susan Broughton says

Heather says
I’m not a huge fan of beef + cheese (strange coming from a Wisconsinite, I know), but the recipe looks great… so, either I’d omit the cheese, or swap the beef for a butterflied pork loin!
Carolyn says
Do it! Sounds fabulous! 🙂

Marcia Little says
Carolyn you have some of the best recipes, this one looks grate too, hehe. I’m thinking it needs a slower melting cheese in it though, so that it doesn’t all ooze out. Like a smoked gouda? Mmmm, gonna make soon.
Carolyn says
That would be tasty too!
olivia Wiley says
cannot wait to try this recipe! It looks so good!
Tracie Cooper says
I love flank steak and I planning to try this recipe very soon! It looks delicious~
Wanda McHenry says
I really like that the Saber grill uses 30% less fuel. We grill year round, so we go through a good amount of propane. Also, your recipe looks fabulous! I will have to give it a try.
Erin says
This recipe looks fantastic! I’ve never heard of Saber but I would love a grill without flare ups!!
SusanLevine says
I’m sure the Saber Grill is wonderful but if you can’t get one, for whatever reason, Char Broil makes a “Big Easy” infrared one at a fraction of the price. No flare ups. I know because I own one and really love it.
Rust says
We really enjoy grilling outside when the weather permits and this new grill would be wonderful to use. The recipe sounds delicious!
Chris says
Just found this site and very excited to try so many of the recipes! What is the side shown in the presentation picture (looks similar to rice). Thanks!
Carolyn says
Cilantro lime cauliflower rice https://alldayidreamaboutfood.com/low-carb-cilantro-lime-cauliflower-rice/
Sam says
Do you have any recommendations for making this in the oven in the middle of winter?
Carolyn says
I have seen some rolled flank steak recipes cooked in the oven, I bet a quick google search would tell you temps and times!
Julian says
Made this the other day using pre marinaded ‘carne asada’ flap meat which is readily available in grocery stores in So Cal. It’s popular for steak tacos and burritos. Similar to flank steak, but not as tender. Flank steak is not common in stores around here.
It came out really good! Will make this again for sure… and try to stuff more cheese into it.
Liz says
The best of both worlds in this recipe! My boys will love it!
Eden says
So unique! What a fun idea and it looks delicious!
Becky Hardin says
This is an absolute must to make! Full of flavor and so delicious.
Taylor says
This idea is brilliant!! So flavorful and delicious!
Jocelyn says
What an absolutely mouthwatering way to serve flank steak for dinner! Love that gooey cheese!
