Brown ground beef in a large skillet over medium-high heat. Drain any grease.

Stir in Worcestershire sauce, ketchup, minced onion, salt, and pepper. Simmer for 5 minutes.

Lay cheddar cheese in the center of each tortilla. Spoon beef mixture on top.

Add a drizzle of mustard, a bit more ketchup (if you like), and tomato slices.

Roll up burrito-style.

Grill wraps for 3–5 minutes until golden with grill marks.

Gently open the wrap, add lettuce and red onion, re-roll and cut diagonally.

Serve warm and enjoy every bite!
