Really easy to make and tastes great!
Bring the broth and 1 can of chiles to a boil in a large skillet. Add the chicken, reduce the heat and simmer for about 15 minutes or until chicken is done turning once. Remove the chicken to a plate and reserve the cooking liquid for later. Allow chicken to cool and shred meat.
Saute 1 can of chiles and onion in heated olive oil for 3 minutes or until soft. Add the reserved liquid, enchilada sauce, milk, cream cheese, Monterey Jack, and stir well. Stir in shredded chicken, cook for 2 minutes. Remove from heat.
Coat a 2-quart casserole with cooking spray and place 4 tortillas in the bottom. Spread 2 cups of chicken mixture over tortillas. Repeat layers twice ending up with the chicken mixture on top. Top with crushed tortillas and cheddar cheese.
Bake at 350 degrees for 30 minutes or until thoroughly heated. Let stand for at least 10 minutes before serving.
