In a small bowl, mix mayonnaise, ketchup, mustard, vinegar and sugar. Stir until smooth. Taste and adjust sweetness or tang. This sauce is the heart of the wrap.

Heat a skillet over medium heat. Add ground beef and season with salt and pepper. Cook until browned, breaking it into small pieces. Drain excess fat if needed. The beef should be juicy and flavorful.

Place the tortillas in a dry pan or microwave briefly. Warm wraps are soft and easier to roll. Avoid over-heating so they don’t tear.

Lay a tortilla flat. Spread a generous layer of special sauce. Add cooked beef evenly over the sauce. Place a slice of cheddar cheese on top while beef is warm. The cheese will melt slightly.

Sprinkle shredded lettuce over the cheese. Add chopped onions and pickle slices. Spread ingredients evenly. The fresh vegetables give crunch and balance.

Fold the sides of the tortilla inward. Roll tightly from bottom to top. Make sure all ingredients are enclosed. Cut the wrap in half if desired for easier handling.

Place the wrap on a plate and serve immediately. Extra sauce can be drizzled on top. Pair with fries or a salad if desired. Enjoy the Big Mac flavor in every bite.
