Add in the cooked chicken, chicken broth, beans, chiles, and seasoning. Bring to a boil, stirring often, and then reduce heat to simmer. Simmer uncovered for 30-45 minutes, or until it's the thickness you desire. Stir occasionally. I let mine simmer for a full hour to let all the flavors blend fully and to get a nice thickness. It would have been ready to go after 30 minutes, so just do what you like best! (See below for Crock Pot Instructions)
