In a large skillet, cook bacon over medium heat until crispy. Remove to a paper-towel lined plate and let cool. Once cool enough, crumble bacon and set aside. Wipe out most of the grease from the pan, allowing some to remain.
Heat the olive oil in same skillet over medium heat. Add diced onions and sauté for a few minutes. Add 1/4 cup of the barbecue sauce to the onions and sauté for another few minutes, until onions are softened and sauce reduces slightly. Turn off heat and set aside.
Place ground chicken or turkey in a large bowl (or grind your own!) Add bacon and onion mixture, and then add Panko, bell peppers, remaining 1/4 cup of barbecue sauce and all the spices. Stir until combined, then fold in the cheddar.
Form into 4 patties. Refrigerate for 30 minutes.
Grill burgers, or cook in skillet with olive oil until done all the way through.
