01 - In a small bowl, combine mayonnaise, ketchup, mustard, diced pickles, white vinegar, smoked paprika, and a pinch of sugar. Stir until fully incorporated and refrigerate until ready to use.
02 - Divide the ground beef into 8 equal portions and gently roll each into a loose ball without overworking the meat.
03 - Set a large non-stick skillet or griddle over medium-high heat and allow it to come to full temperature before adding beef.
04 - Place 2 beef balls on the hot surface per batch. Lay a flour tortilla over each ball and press firmly with a sturdy spatula, spreading the beef thin across the underside of the tortilla with the meat in direct contact with the pan.
05 - Distribute kosher salt, black pepper, and garlic powder evenly over the exposed beef. Cook for approximately 2 minutes, pressing down periodically, until the edges of the beef turn crisp and deeply browned.
06 - Flip each taco so the tortilla side contacts the pan, then immediately scatter shredded cheddar over the beef. Cook for 1 additional minute until the tortilla is golden and the cheese is fully melted.
07 - Cook the remaining beef balls and tortillas in batches following the same technique, adjusting heat if necessary to maintain consistent browning.
08 - Layer shredded iceberg lettuce, diced tomato, finely diced red onion, and sliced dill pickles over each cheesy beef taco. Finish with a generous drizzle of the reserved burger sauce.
09 - Transfer tacos to a serving platter and enjoy right away while the beef edges remain crisp and the cheese is hot.
