To make this recipe gluten free, verify that the barbecue sauce, Worcestershire sauce, soy sauce, pork and beans, ketchup, spicy brown mustard, and bacon are all certified gluten free, as many packaged brands may contain hidden gluten or wheat-based additives. Replace the soy sauce with a certified gluten-free tamari if needed. If cross-contact is a concern, use clean cookware, utensils, and prep surfaces throughout preparation.
