This meal began as a mix-and-match of our favorite quesadilla and guacamole recipes and evolved into a legendary family favorite in no time. Serve with salsa and sour cream, over rice and re-fried beans or whatever else you like.
Pit avocado and mash in a small mixing bowl with the lime juice. Add garlic, green onion, tomato, yellow onion, bell pepper, salt and chili powder. Mix thoroughly. Cover and refrigerate for 30 minutes.
Heat oil over medium heat in a medium skillet. Place tortilla in skillet and top with 1/3 cup cheese. When cheese has melted and tortilla is slightly browned, spoon on some guacamole and top with another tortilla. Flip, and allow the second tortilla to brown.
Remove from heat and cut into wedges. Repeat with remaining ingredients.
