Cook the chicken in water. I always add salt, pepper & garlic while it is cooking. If you keep at medium-high heat, your chicken will not boil over and you do not have to watch it as often. While the chicken is cooking, combine the chicken broth, corn, refried beans, rotel, cream of chicken and cumin into a large pan and place on the stove. Cook at medium-high heat until hot. Shred chicken with a fork and add to soup. Keep hot until you serve. Serve with tortilla chips and topped with shredded cheese.
