Mix ground beef, ketchup, Hamburger Seasoning and Worcestershire sauce in medium bowl until well blended. Shape into 4 patties.
Grill over medium heat 4 to 6 minutes per side or until burgers are cooked through (internal temperature of 160 degrees F). Add cheese slices to burgers 1 minute before cooking is completed. Toast rolls on the grill, open-side down, about 30 seconds or until golden.
Serve burgers on toasted rolls with bacon slices, if desired. Garnish with desired toppings and condiments.
