To make this Cranberry Meatballs Recipe gluten free, ensure the turkey meatballs are certified gluten free, as many prepared meatballs contain breadcrumbs or fillers made with wheat. In addition, verify that the chili sauce and jellied cranberry sauce are labeled gluten free and free from cross-contamination. If needed, homemade gluten-free meatballs may be used as a substitute for store-bought versions.
