My gluten-free barbecue meatball subs are the ultimate summer meal—messy, saucy, and packed with fresh flavor. Juicy homemade meatballs are baked, tossed in tangy barbecue sauce, and finished under the broiler for a caramelized touch. Served on Canyon Bakehouse gluten-free sub rolls with melty Colby Jack cheese and a crisp, tangy slaw, this easy dinner is perfect for a crowd or a weeknight win.
