01 - In a small bowl, combine mayonnaise, ketchup, mustard, diced pickles, white vinegar, smoked paprika, and sugar. Stir until evenly incorporated, then 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 temperature.
04 - Place 2 beef balls on the hot skillet per batch. Drape 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 side in direct contact with the pan.
05 - Distribute salt, pepper, and garlic powder evenly over the exposed beef. Cook for 2 minutes, applying gentle pressure occasionally, 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 - Work through the remaining beef balls and tortillas in batches, maintaining consistent heat and technique.
08 - Layer shredded lettuce, diced tomato, finely diced red onion, and sliced dill pickles over each taco, then finish with a generous drizzle of the reserved burger sauce.
09 - Plate the tacos right away while the tortillas are still crisp and the beef is hot.
