Season the ground beef balls with salt and pepper.

Heat a skillet over medium-high heat and cook the beef balls, smashing them down to form patties.

Cook until browned and cooked through, then place a slice of American cheese on each patty to melt.

Warm the flour tortillas in a separate pan or microwave.

Prepare the burger sauce by mixing mayonnaise, ketchup, pickle relish, apple cider vinegar, and ground black pepper in a bowl.

Assemble the tacos by placing a cheese-topped patty in each tortilla, adding sweet and spicy pickles, shredded lettuce, and a drizzle of burger sauce.
