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 roll gently into loose balls without overworking the meat.
03 - Set a large non-stick skillet or griddle over medium-high heat and allow it to get thoroughly hot before adding beef.
04 - Place 2 beef balls on the hot skillet per batch. Set a tortilla over each beef ball and press down firmly with a sturdy spatula until the beef spreads thin across the underside of the tortilla, with the beef side directly against the pan.
05 - Sprinkle kosher salt, black 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 sprinkle shredded cheddar on top of the beef. Cook 1 additional minute until tortillas are golden brown and cheese is fully melted.
07 - Cook the remaining beef balls and tortillas in batches following the same smash-and-flip technique.
08 - Top each tortilla with shredded lettuce, diced tomato, red onion, sliced dill pickles, and a generous drizzle of the prepared burger sauce.
09 - Plate the tacos and serve right away while the beef edges are still hot and crispy.
