In a large skillet, fry bacon over medium heat until crisp. Remove bacon and drain on paper towels, reserving 1/4 cup of bacon grease in the skillet.

Stir in pork and beans, mustard, maple syrup, ketchup, molasses, brown sugar, salt, pepper, and crumbled bacon into the skillet with the onions. Mix thoroughly.
