1. Prepare the Big Mac Sauce by mixing mayonnaise, finely diced pickles, mustard, ketchup, and paprika in a bowl. Chill until needed.
2. In a skillet over medium heat, cook the ground beef with half of the diced onion. Season with salt, pepper, garlic powder, onion powder, and Worcestershire sauce. Cook until the beef is browned and onions are soft. Drain excess grease and transfer to a bowl.
3. Warm tortillas by microwaving briefly or heating on a pan to soften.
4. On each tortilla, spread the Big Mac sauce, then layer shredded lettuce, sliced pickles, cooked beef mixture, remaining onions, and shredded cheese. Roll and fold into wraps.
5. Serve immediately or store leftover wraps in plastic wrap inside an airtight container for 3-4 days, removing lettuce before storing to avoid wilting.
