01 - In a small bowl, whisk together mayonnaise, ketchup, mustard, chopped pickles, garlic powder, onion powder, smoked paprika, salt, and pepper until smooth and well combined. Set aside to allow flavors to meld.
02 - Divide ground beef into 8 equal portions, rolling each into a ball approximately 2 oz each. Lightly season each ball with salt and pepper on all sides.
03 - Place a large cast iron skillet or griddle over medium-high heat and allow it to become thoroughly hot, approximately 3-5 minutes. The surface should be smoking slightly before adding 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 and press down firmly with a sturdy spatula or burger press, flattening the beef to match the tortilla size.
05 - Cook for 2-3 minutes without disturbing, allowing the beef to develop a deep brown crust and crispy edges. The fat should render and create a crispy, lacy edge.
06 - Carefully flip each assembly so the tortilla contacts the skillet directly. Place a cheese slice on each beef patty. Continue cooking for 1-2 minutes until the tortilla is golden brown and toasted, and the cheese is completely melted.
07 - Remove finished tacos to a platter and repeat the cooking process with remaining beef balls and tortillas. Keep cooked tacos warm in a low oven if desired.
08 - Top each smash burger taco with shredded lettuce, diced tomatoes, sliced red onion, and pickle chips. Drizzle generously with the prepared smash burger sauce. Serve immediately while tortillas remain warm and beef is juicy.
