Preheat oven to 375°F
In a small bowl mix the sauce ingredients together, set aside.
Heat the skillet over medium-high heat.
Cook the bacon until nearly done, about 3 minutes. (It will finish cooking in the oven.)
Remove bacon; set aside.
Add the onions to the bacon renderings and cook until they start to soften, about 3 minutes.
If there is an excess of bacon renderings, drain now.
Add pork and beans to the onion in the skillet, stir well.
Pour in the sauce mixture, stirring until it is fully incorporated.
Lay the bacon across atop of beans, some slices may need to be cut to fit any holes.
Place in oven and bake uncovered for an hour.
Remove from oven and allow to cool for a minute or two.
Serve from the skillet or transfer to a serving bowl or platter; enjoy.
