Grilled Cheeseburger Wraps

1 lb ground beef
1 tablespoon Worcestershire sauce (I used a little more to taste)
1 tablespoon ketchup
1 teaspoon dried minced onion
pepper and salt to taste
5 flour tortillas (the larger ones)
shredded cheddar cheese
sliced tomatoes
yellow mustard

Brown ground beef in large skillet and drain. Add Worcestershire sauce, ketchup, dried onion, and salt and pepper to the beef and simmer for 5 minutes. Sprinkle shredded cheese down center of each tortilla. Add a few heaping tablespoons of the beef mixture on top of the cheese. Spread some mustard on top of the beef along with some slices of tomato. Roll up tortilla burrito-style and place wraps on preheated indoor grill (I used my George Foreman).
Grill wraps for about 5 minutes until cheese is melted. Cut on a diagonal and serve immediately!
