Bring a small skillet sprayed with nonstick spray to medium heat. Cook and crumble soy chorizo until hot, about 3 minutes. Transfer to a bowl.
Remove skillet from heat; clean, if needed. Re-spray and return to medium heat. Add egg whites/substitute and let coat the skillet bottom. Cover and cook for 2 minutes, or until solid enough to flip.
Carefully flip egg “crust.”. Top with salsa, cheese, and chorizo, leaving a 1/2-inch border. Cover and cook for 1 minute, or until crust is fully cooked and cheese has melted.
