Preheat oven to 350°F (175°C).

In a large ovenproof container, combine pork and beans, prepared mustard, molasses, Worcestershire sauce, Tabasco sauce, ketchup, chopped onion, chopped celery, chopped bell pepper, and barbecue sauce.

Stir well to ensure all ingredients are evenly distributed.

Lay bacon strips on top of the bean mixture.

Cover the container and bake for approximately 30 minutes, or until the bacon is cooked and the beans are heated through.

Remove from oven and let stand for a few minutes before serving.
