Preheat your smoker to 300º F (148° C).
Using your favourite cooking oil, sauté bell peppers and onions in a frying pan until peppers are tender and onions are clear.
Add canned chilli to the pan to heat thoroughly and set aside once warm.
In a bowl, mix ground beef, salt, pepper, garlic powder and Worcestershire sauce together. Add any other seasonings you wish to add.
Form the beef mixture into small balls of approx. 8-12 ounces each, or around palm-size.
Using a beer can, lightly press into each meat ball to simultaneously flatten & add a small cavity to the center to make space for the filling.
Wrap a slice of bacon around the sides of the burger as an external coating.
Spoon chilli mixture into the center as a filling and top with cheese if you wish.
Place burgers inside smoker and cover for 45 minutes. You can flip part-way through if you want your burger to be seared on both sides.
Once cooked, remove from smoker and place in buns with your favourite salad, toppings & condiments.
