Cook bacon in a large skillet over medium-high heat. Remove bacon and set aside. Reduce heat to medium.
Add onions and bell pepper to bacon grease in skillet (add a bit of olive oil if there is not enough bacon grease). Cook for 2 minutes. Add garlic and cook one minute more. Add ground turkey and cook until turkey is browned and cooked through.
Sprinkle brown sugar over turkey mixture; mix thoroughly. Add all remaining ingredients and stir well.
Simmer for 30 minutes over low heat.
Lightly butter hamburger or slider buns and broil until lightly toasted. Top bottoms with sloppy joe mixture, top with cheese and place under broiler for 1-2 minutes until cheese is melted. Add jalapenos, if desired. Enjoy!
