In a small bowl, whisk the eggs. Coat a large skillet with cooking spray. Add eggs; cook and stir over medium heat until completely set.
Place tortillas on a griddle. Spoon eggs over half of each tortilla; sprinkle with cheese, bacon and onion. Fold over and cook over low heat for 1-2 minutes on each side or until cheese is melted. Serve with sour cream and salsa.
