In a large skillet coated with cooking spray cook the beef on medium till almost cooked through but still a little pink (about 7-10 minutes). Break beef up as it cooks.
Add worcestershire, 1 tablespoon ketchup, grated parmesan, dried onion flakes, salt, and pepper to the beef. Mix together until thoroughly combined.
Continue cooking until beef is cooked all the way through and is no longer pink.
Turn on indoor grill to 350 or you can also use a grill plan.
In the center of each wrap place a slice of cheese and ½ cup of the beef mixture. Add tomato and lettuce. Then some ketchup and mustard. Roll the wrap and place seam side down on grill. Once there are grill marks turn over. Grill for another 2-3 minutes then remove.
