Mix Up the Burger Magic: In a large bowl, combine the ground beef, Worcestershire sauce, ketchup, dried minced onion, salt, and pepper. Give it a good mix to make sure the seasonings are evenly distributed throughout the meat.

Fire Up the Flavor! Preheat your grill to medium-high heat. Form the ground beef mixture into patties slightly larger than the diameter of your tortillas.  Grill the patties for 3-4 minutes per side, or until cooked through to your desired doneness

Warm Those Wraps: While the burgers are sizzling, warm up your tortillas. You can do this by placing them directly on the grill for a few seconds per side, just until they become warm and pliable. Alternatively, heat them in a skillet over medium heat for about 30 seconds per side

Wrap It Up Right: Lay a warmed tortilla flat on a plate.  Spread a layer of mustard (optional) on one half of the tortilla.  Top it generously with shredded cheese, a perfectly cooked burger patty, juicy tomato slices, and crisp lettuce (don't forget your other favorite toppings

The Grand Finale: Fold the bottom half of the tortilla over the filling, then fold in the sides to create a neat package.  Gently fold the top flap down to secure the wrap.  Repeat with the remaining tortillas and ingredients. 

Now you're ready to devour your delicious and mess-free Grilled Cheeseburger Wrap!
