Preheat a grill to medium-high.
Combine chuck with diced sausage, pepper, and onion. Portion off enough meat to make a burger, and shape the meat into a bowl to hold the Worcestershire and grilling seasoning. Pour just enough Worcestershire and grilling seasoning into the burger bowl and mix well to combine. Shape into a patty. Repeat with remaining meat mixture to make a total of 8 burgers.
Place burgers on the grill. Brush the burgers with your favorite barbecue sauce as they cook. Once they are almost cooked to your desired degree of doneness, divide the following toppings over: the sauteed mushrooms, 2 slices of bacon, and 1 slice of cheese, in that order. Cook just until cheese is melted and toppings are heated through. Serve burgers on a hamburger bun or sourdough toast.
