Cook 4 ounces ground beef with 1 tablespoon taco seasoning until browned. Set aside. Also chop ½ tomato and shred ¼ cup lettuce and set aside.
Place one small buttered flour tortilla on the skillet. Toast until golden, flip and toast the other side. Remove from pan and repeat with another tortilla. Top the second tortilla with grated cheddar and cover with the first tortilla. Remove from pan and repeat with a third tortilla, topping the cheese with the first two tortillas. The layers should be: crispy tortilla, cheese, crispy tortilla, cheese, crispy tortilla.
Do this all over again so you have two of these double-decker quesadillas. Yes, you just created two of these.
Leave one quesadilla in the pan and top with more cheese. Add beef, tomatoes, and more cheese. Top with the second quesadilla and press to set. Flip and cook the other side until cheese is fully melted. Serve with lettuce and guacamole and an unsigned final will and testament.
