Preheat oven to 350 degrees F or smoker to 225-250 degrees F.
In a large skillet, cook the bacon until crispy.
Once cooked, remove from skillet, keeping the grease from the bacon in the skillet.
Add onion, bell pepper, and jalapeno to the skillet and cook until softened about 7-8 minutes.
To the skillet, add bacon, baked beans, pineapple brown sugar, tomato sauce, mustard powder, and Worcestershire and stir well to combine.
If baking in the oven, pour bean mixture into a 9x13" baking dish.
If smoking the beans, pour into a cast iron or aluminum baking dish.
Bake in the oven for an hour or smoke in the smoker for 3 hours.
Serve and enjoy!
