Enjoy this hearty American classic with burgers, hot dogs, or BBQ chicken.
Preheat your oven to 350°F. In an oven-safe skillet over medium heat, add the olive oil, diced onion, green bell pepper, and minced garlic. Sauté.
Stir in the apple cider vinegar, ketchup, mustard, brown sugar, barbecue sauce, salt, and pepper. Mix well and add the baked beans with juices. Bring the mixture to a gentle simmer.
Place the skillet in the oven and bake for 40-60 minutes. Remove the skillet from the oven and let the beans cool slightly before serving. Garnish with fresh herbs if desired.
