01 - Combine mayonnaise, ketchup, mustard, chopped pickles, garlic powder, onion powder, smoked paprika, salt, and pepper in a small bowl. Mix thoroughly until smooth and well incorporated. Set aside at room temperature for flavors to meld.
02 - Divide ground beef into 8 equal portions, approximately 2 oz each. Roll each portion into a loose ball. Season all surfaces lightly with salt and pepper just before cooking to prevent moisture loss.
03 - Heat a large cast iron skillet or griddle over medium-high heat until smoking hot, approximately 5 minutes. The surface must be sufficiently hot to create proper crust on the beef.
04 - Working in batches to avoid overcrowding, place 2-3 beef balls on the hot skillet. Immediately place a tortilla directly on top of each ball. Press down firmly with a sturdy spatula or burger press, flattening the beef thinly against the tortilla. Cook for 2-3 minutes until deeply browned and crispy at edges.
05 - Flip each assembly so the tortilla contacts the skillet directly. Place one cheese slice atop each beef patty. Continue cooking for 1-2 minutes until tortilla is golden brown and cheese is fully melted. Remove from skillet and set aside.
06 - Repeat cooking process with remaining beef balls and tortillas. Hold finished tacos in a warm oven or under foil if desired, though serving immediately yields best texture.
07 - Top each smash burger taco with shredded lettuce, diced tomatoes, sliced red onion, and pickle chips. Drizzle generously with prepared smash burger sauce. Serve immediately while tortillas remain warm and beef edges retain their crispy texture.
