01 - In a small bowl, combine mayonnaise, ketchup, mustard, diced pickles, vinegar, smoked paprika, and sugar. Mix thoroughly 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 temperature.
04 - Place 2 beef balls on the hot skillet per batch. Lay a tortilla over each ball and press flat with a sturdy spatula until the beef spreads thin across the underside of the tortilla, with the beef side in direct contact with the pan.
05 - Distribute salt, pepper, and garlic powder evenly over the exposed beef surface.
06 - Cook for 2 minutes, pressing down occasionally, until the beef edges are crisp. Flip so the tortilla side contacts the pan, then scatter cheese over the beef. Cook 1 additional minute until the tortillas are golden and the cheese is fully melted.
07 - Cook the remaining beef balls and tortillas in batches following the same method.
08 - Top each taco with shredded lettuce, diced tomato, red onion, sliced pickles, and a generous drizzle of burger sauce.
09 - Plate the tacos and serve right away while the shells are still hot and crispy.
