Mix soup and chilis together. Set half of the mixutre aside. Add chicken and 4 ounces of cheese to half of the soup mixture. Divide mixutre into 8ths and spread over tortillas. Roll each one enchilada-style. Place in a sprayed baking dish in a single layer. Spread the rest of the soup mixture over the enchiladas. Cover and bake at 350° for 30 minutes. Five minutes before they are done, uncover and sprinkle the rest of the cheese on top.
