Instead of asking "why stuff a burger with bacon and cheddar?"...ask yourself WHY NOT?!?
1 lb ground beef chuck
In a large bowl combine ground beef, salt, pepper and Worcestershire sauce together. Form the meat into 8 equal portioned patties. Place patties on a plate and cover under refrigeration until ready to use.
In a small bowl, combine cheddar cheese, bacon, barbecue sauce and onion together. To stuff burgers, place a small about of cheese and bacon mixture in the middle of four patties. Cover the filled patties with the plain patties, securing the burgers by crimpling the sides with your fingers. Chill burgers until ready to cook.
Broil, grill or sauté burger until cheese has melted and the meat is cooked well. Place on toasted hamburger buns and top as desired. The filling in these burgers will be VERY hot, be careful when eating.
