# How To Make It:
01 - Combine mayonnaise, ketchup, yellow mustard, sweet pickle relish, white vinegar, garlic powder and paprika in a small bowl; season with salt and freshly ground black pepper, taste and adjust. Cover and refrigerate until assembly.
02 - Divide the ground beef into 8 equal portions (about 2 ounces each) and gently form loose balls without compacting the meat.
03 - Brush the cut sides of the brioche buns with melted butter. Toast cut side down on a preheated skillet or grill over medium heat until golden brown; transfer to a plate and keep warm.
04 - Heat a griddle or large cast-iron skillet over high heat until very hot. Lightly oil the surface just before adding the meat to prevent sticking.
05 - Place 2 to 4 meat balls on the hot surface (work in batches). Immediately press each ball firmly with a spatula or burger press to ~1/4-inch thickness. Season with kosher salt and freshly ground black pepper. Cook 1 to 1 1/2 minutes until edges are deeply browned and juices appear on top, flip, top each patty with a slice of cheese and cook another 1 minute until cheese melts.
06 - Spread secret sauce on both bun halves. On each bottom bun layer shredded lettuce, a cheesy smashed patty, two pickle chips and a few rings of sliced red onion. Cap with top buns.
07 - Serve immediately while hot alongside preferred sides. Keep any extra patties warm in a low oven until ready to assemble.
