Cut the bacon into 1/2" pieces, and fry them in a large sauté pan. While the bacon is cooking, dice up the onion and jalapeños in 1/4" chunks. Remove the bacon from the pan and place it on a plate or in a bowl. Reserve the bacon fat in the pan and sauté the jalapeños and onions in the bacon fat.
While the vegetables are cooking, empty the four cans of white beans into an oven safe pot (enameled cast iron works very well). Place the pot over medium heat, and add the bacon, veggie mixture, one bottle of Plowboys BBQ Bean Buddy Bean Starter and two tablespoons Plowboys Yardbird Rub. Stir the ingredients until combined.
Preheat your grill (we used a Yoder Smokers YS640 pellet cooker) to 350°F. Place the pot of beans on your grill and let them cook for at least one hour. Stir regularly to make sure the beans at the bottom of the pot do not burn.
Once the beans have finished cooking we suggest you place them in an airtight container to sit in the refrigerator overnight. This will allow the beans to set up and the flavors to continue to combine. Serve and enjoy!
