To make this recipe gluten free, verify that the taco seasoning mix, ranch dressing mix, canned tomatoes, chili beans, pinto beans, and tortilla chips are certified gluten free, as some packaged products may contain gluten or be subject to cross-contact. If preferred, use homemade taco seasoning and homemade ranch-style seasoning to better control ingredients. Also ensure that the soup is prepared with clean utensils and cookware if it is being made in a shared kitchen.
