When hot, place tortilla in pan. Cook until tortilla is slightly browned on the bottom. Flip.
Onto flipped tortilla crack one egg and with a fork scramble it around the tortilla. Sprinkle garlic salt around to taste. Place sliced mushrooms in single layer on top of egg-topped tortilla. Sprinkle with grated cheese. Spread salsa on top. Cook with a lid until egg is done and cheese is melted.
NOTE: Do not overcook or tortilla will burn on the bottom. Slide tortilla onto a dinner plate and enjoy.
