Begin by preheating your barbecue grill to high heat. This ensures that it's ready for cooking the sausage and brisket later on, imparting a delicious smoky flavor to the beans.
In a skillet or on a griddle, cook the bacon until it's crispy and golden brown. Once cooked, set the bacon aside and reserve 3 tablespoons of the bacon fat for later use.
Place the sausage links on the preheated grill and cook them until the surface develops a delicious charred exterior, which typically takes about 20 minutes. This step adds depth of flavor to the beans.
Around the 15-minute mark of grilling the sausage, add the brisket to the grill to give it a bit of charring as well. This enhances the overall flavor profile of the beans.
In a large saucepan, heat the reserved bacon fat over medium-low heat. Add the minced white onion, red bell pepper, and jalapeno pepper to the saucepan. Saute the vegetables for about 5 minutes or until the onions become translucent and fragrant.
Dice the cooked bacon, sausage, brisket, and pulled pork into bite-sized pieces. Add them to the saucepan with the sauteed aromatics.
Increase the heat to medium and cook the meat mixture for 2 minutes to allow the flavors to meld together.
Pour in the cans of Bush's Best Original Baked Beans (including the liquid) into the saucepan, followed by the barbecue sauce, mustard, sorghum molasses, and brown sugar. Stir everything together until well combined.
Bring the bean mixture to a gentle boil, then reduce the heat to low and let it simmer uncovered for 15 minutes, stirring occasionally. This allows the flavors to intensify and the sauce to thicken slightly.
Once the beans are heated through and the flavors have melded beautifully, remove the saucepan from the heat.
Serve the baked beans hot, alongside your favorite barbecue dishes or as a delicious standalone meal.
