Prep the lettuce: Separate and rinse the leaves. Pat them dry well so they stay crisp.
Set aside on a towel.
Mix the sauce: Stir the mayo, sugar-free ketchup, mustard, and pickle juice with paprika. Adjust with salt and pepper. Chill while you cook the beef.
Season the beef: In a bowl, combine ground beef with salt, pepper, garlic powder, onion powder, and Worcestershire.
Don’t overmix; you want it tender.
Cook the beef: Heat oil in a large skillet over medium-high heat. Add beef and break it into crumbles. Cook 6–8 minutes until browned with crispy bits.
Melt the cheese: Turn heat to low.
Spread the cooked beef into an even layer and top with cheese slices or shredded cheese. Cover 1–2 minutes until melted.
Assemble the wraps: Lay two lettuce leaves overlapping for a sturdy base. Spoon on the cheesy beef.
Add onion, pickles, tomato, and avocado if using.
Add the sauces: Drizzle special sauce, plus mustard or sugar-free ketchup if you like. Go light so the wraps don’t get soggy.
Fold and serve: Fold the sides in, then roll like a burrito, or keep them open-faced and eat taco-style. Serve right away while warm.
