Add the eggs, cottage cheese, salt and pepper to a blender and blend until mostly smooth. This creates extra fluffy, creamy eggs that stay soft even after reheating.
Cook the chorizo in a large nonstick skillet over medium heat, breaking it up, for 6 to 7 minutes until browned. Add the bell pepper and cook for 2 to 3 minutes more. Transfer to a bowl, leaving about 1 tablespoon of fat in the pan.
Reduce the heat to medium-low and pour in the egg mixture. Stir gently with a spatula until soft curds form and the eggs are just set, 3 to 4 minutes. Fold in the chorizo mixture.
Warm the tortillas so they are flexible. Sprinkle cheese down the center of each one, top with the egg filling, salsa and cilantro, then fold in the sides and roll tightly.
Wipe out the skillet and place the burritos seam side down over medium heat. Cook for about 2 minutes per side until golden and sealed.
Serve right away, or cool completely, wrap each burrito in foil and freeze for easy weekday breakfasts.
