Preheat the oven to 375°F and generously grease a non-stick rimmed sheet pan with (avocado oil) cooking spray.
Place the veggie ingredients onto the pan and toss together. Spread in an even layer and roast for 15 minutes.
Meanwhile, mix all the meat ingredients in a bowl with your hands until well combined.
Mix the roasted veggies and spread back out into an even layer. Sprinkle the beef (or turkey) mixture in small clumps on top.
Bake for another 15-20 minutes, until the meat is crispy. Keep the oven on after baking for later.
While the beef mixture bakes, blend the cottage cheese egg mixture in a blender until smooth.
Pour the liquid mixture over the entire sheet pan, sprinkle with shredded cheese, and bake for another 10-12 minutes or until the egg is mostly set.
Let cool for 10 minutes, then cut the egg mixture into 12 rectangles.
Fill each tortilla (12 tortillas total) with 1 heaping tablespoon salsa, baked egg rectangle and spinach. Roll the tortilla up, tucking the sides inwards and rolling tightly.
Place each burrito onto the now-empty pan, spray with avocado oil (or drizzle with a bit of avocado oil) and bake for 5-7 minutes, until crisp and lightly golden.
Let cool for 10 minutes and enjoy!
