Ingredients

• 10 slices bacon halved
• 1 yellow onion finely diced
• 1/2 green bell pepper finely diced
• 54 oz can pork and beans or equivalent number of smaller cans
• 4 Tbsp ketchup
• 1/4 cup molasses
• 2/3 cup brown sugar
• 1/4 cup cider vinegar
• 2 tsp dry mustard

Instructions
Cook bacon about half way through (in whichever way you want), and set aside to drain on a paper towel.
Preheat oven to 325 degrees and set rack to the lower-middle rack position.
In a deep skillet, heat about 2 Tbsp of bacon grease (or butter) over MED heat. Add diced onion and green pepper and saute about 5 minutes, until softened.
Add remaining ingredients and stir to combine well. Let mixture simmer for a minute or so.
While the mixture is simmering, grease a 13×9 baking dish.
Pour beans into the prepared baking dish and lay cooked bacon on top of the beans.
Bake for 2-3 hours, depending on your desired consistency.
Let the beans stand for 5 minutes before serving.
