In a small bowl, whisk the butter with the garlic, Parmesan, parsley, and salt.
Breadsticks
Preheat the oven to 325F and line a baking sheet with parchment paper. Grease the parchment paper.
In a large bowl, whisk together the almond flour, coconut flour, protein powder, baking powder, salt, and garlic powder. Add the olive oil, eggs, and egg whites and mix until well combined. Let sit 5 minutes to firm up.
Divide the dough into 12 even portions. Using wet hands, form each portion into a log about 1 inch wide and 4 inches long. Place on the prepared baking sheet 2 to 3 inches apart (they will spread a bit).
Brush the sticks with half of the garlic butter mixture. Bake about 15 minutes, until the breadsticks are golden brown and just firm to the touch.
Remove and let cool 10 minutes, then brush with the remaining garlic butter. Serve warm.
