Prepare the Savory Filling
Brown the Meat: In a medium skillet over medium-high heat, cook the ground beef.
Season: Add salt and black pepper. Cook until the beef is browned and slightly crisp. Drain excess fat and set aside.
The Chip-Crust Coating
Crush the Chips: Pulse your favorite chips in a blender or crush them in the bag until they reach a coarse crumb consistency. Pour into a wide bowl.
The Adhesive: Dip one side of a tortilla into the ketchup or barbecue sauce, ensuring a thin, tacky layer.
The Crust: Immediately press the sauced side firmly into the crushed chips until fully coated.
The Gravity-Fold Bake
Preheat: Set your oven to 350°F (180°C).
The Shape: Drape each coated tortilla over two bars of a wire cooling rack placed over a baking sheet. This ensures the taco "U" shape and 360-degree air circulation.
Bake: Cook for 15 minutes.
Note: The shells will feel slightly soft immediately out of the oven but will turn "shatter-crispy" as they cool for 2 minutes.
Assembly
Layer: Carefully remove the crisp shells from the rack.
Fill: Stuff with shredded lettuce, the seasoned ground beef, and an extra drizzle of sauce.
