01 - In a small bowl, mix mayonnaise, ketchup, mustard, chopped pickles, garlic powder, onion powder, smoked paprika, salt, and pepper until well combined. Set aside.
02 - Divide ground beef into 8 equal balls (about 2 oz each). Season lightly with salt and pepper.
03 - Heat a large cast iron skillet or griddle over medium-high heat until very hot.
04 - Working in batches, place 2-3 beef balls on the hot skillet. Immediately top each with a tortilla and press down firmly with a spatula or burger press to flatten the beef thinly against the tortilla.
05 - Cook for 2-3 minutes, until the beef is browned and crispy at the edges.
06 - Flip each taco so the tortilla is now on the skillet and the beef is facing up. Place a slice of cheese on each patty. Cook for another 1-2 minutes, until the tortilla is golden and the cheese is melted.
07 - Remove from skillet. Repeat with remaining beef and tortillas.
08 - Top each smash burger taco with lettuce, tomato, onion, pickle chips, and a generous drizzle of smash burger sauce. Serve warm immediately.
