01 - Whisk together mayonnaise, ketchup, mustard, chopped pickles, garlic powder, onion powder, smoked paprika, salt, and pepper in a small bowl until thoroughly combined. Refrigerate until ready to serve.
02 - Divide ground beef into 8 equal portions, approximately 2 oz each. Form into loose balls and season lightly with salt and pepper on all sides.
03 - Place cast iron skillet or griddle over medium-high heat for 3-5 minutes until surface is smoking hot.
04 - Place 2-3 beef balls on hot skillet. Immediately top each with a tortilla and press firmly with spatula or burger press, flattening beef to paper-thin layer against tortilla.
05 - Cook for 2-3 minutes undisturbed until beef develops deep brown crust and crispy edges.
06 - Flip tacos so tortilla contacts skillet directly. Place cheese slice on each patty. Cook 1-2 minutes until tortilla is golden-brown and cheese is fully melted.
07 - Transfer cooked tacos to serving plate. Repeat cooking process with remaining beef balls and tortillas.
08 - Top each taco with shredded lettuce, diced tomatoes, sliced red onion, and pickle chips. Drizzle generously with prepared sauce. Serve immediately while hot.
