Reserve ½ cup Stubb’s Green Chile Anytime Sauce for casserole dish. Marinate the chicken breasts overnight using the remaining Green Chile Anytime Sauce.
Prepare grill for direct heat cooking. Cook chicken breasts over direct heat for approximately 7 minutes per side until they have reached an internal temperature of 165° degrees. Reserve 2 chicken breasts for the casserole dish and serve the remaining chicken with your choice of side dishes.
To prepare the Green Chile Enchilada Casserole, preheat the oven to 350° degrees. Spray a 9x13 baking dish with cooking spray. Chop the two reserved chicken breasts into bite size pieces. Mix the chicken, sour cream, reserved Green Chile Anytime Sauce, black beans, corn and 1 ½ cups of cheese*.
Arrange 5 tortillas in the bottom of prepared baking dish and top with 1/3 of the chicken mixture. Create another two layers of 5 tortillas and 1/3 of chicken mixture and then top with 1 cup of cheese.
Bake for 30 minutes uncovered until bubbly and the cheese is melted. Top with cilantro and serve.
