To make the filling, mix together chopped cooked bacon, cream cheese, and shredded cheese and set aside.

Combine ground beef with Worcestershire sauce, salt and pepper. Divide the mixture into eight, then make four thin patties and place them on a plate. Divide the bacon mixture between the four patties.

Form four more patties from the remaining beef mixture, then place each one on top of the first patties. Seal the edges and flatten them as much possible.

Grill the burgers over a medium-high heat until desired doneness is reached, flipping over half way through cooking time.

Serve the cooked burgers on toasted SmartBuns, with lettuce and low carb tomato sauce.
