In a bowl, mix together mayonnaise, ketchup, pickle juice, chopped pickles, ground black pepper, and paprika until you achieve a smooth, creamy texture.

Heat a large skillet over medium-high heat. Add the ground beef, breaking it apart as it cooks. Brown the meat until it's no longer pink, then stir in salt, black pepper, Spanish paprika, garlic powder, and onion powder. Drain off any excess fat.

Lay out your tortillas and spoon the cooked beef onto half of each. Top with a generous sprinkle of shredded cheese. If desired, add pickles or tomatoes before folding the tortilla in half and gently pressing down to seal.

Place the folded quesadillas into a dry skillet over medium heat. Cook until the bottom is crisp and golden—about 3-4 minutes. Flip and cook the other side until golden and the cheese is completely melted.

Transfer the quesadillas to a cutting board, letting them cool slightly before slicing. Serve with extra burger sauce and your favorite burger toppings on the side.
