Any type of cooked chicken will work in this recipe. I always have frozen rotisserie chicken on hand, so that is what I use. Also, to ensure this recipe is gluten-free, make certain you are using gluten-free chicken, dressings and tortilla strips. The brands I have recommended are all gluten-free. You can find the BBQ sauce and tortilla strips linked below in the Featured Products. Boston Market, Costco or Sam's Club all carry gluten-free rotisserie chickens. I also buy my dry Ranch Dressing mix at Costco.
