Preheat the oven to 375 and line a large rimmed baking sheet with parchment paper.
In the bowl of a large food processor, combine all of the ingredients. Process on high until well combined, scraping down the sides of the processor as needed.
Alternatively, you can mix everything in a bowl by hand, really working the ingredients together to form a cohesive mixture.
Roll into 1½ inch balls and place about 1 inch apart on the prepared baking sheet (you will get about 32 to 36 meatballs). Bake 20 minutes, until browned and cooked through.
