To make this recipe gluten free, use a certified gluten-free ranch dressing, taco seasoning, and tortilla chips, as some packaged versions may contain hidden gluten or cross-contact risks. Also confirm that the rotisserie chicken and shredded cheese are gluten free, since seasoning blends and anti-caking agents can vary by brand. If preparing the salad in a shared kitchen, use clean bowls, utensils, and prep surfaces to help avoid gluten contamination.
