To make these Ranch Chicken Wraps gluten-free, replace the regular flour tortillas with certified gluten-free tortillas. Confirm that the ranch dressing, mozzarella cheese, cooked grilled chicken, seasonings used on the chicken, cilantro, oil, and cooking spray are labeled gluten-free and free from gluten-containing additives. If using store-bought or leftover grilled chicken, check that no wheat-based marinades, sauces, or seasoning blends were used. Prepare the wraps on clean cutting boards, pans, utensils, and prep surfaces to prevent gluten cross-contact.
