Preheat oven to 400 degrees and grease a 9x9 casserole dish.
In a medium bowl, stir together the cornbread mix and the ingredients listed on its packaging. Add diced green chiles, set aside.
In a separate large bowl, combine the shredded chicken and spices. Add black beans, creamed corn, 1/2 cup Monterey Jack cheese, 1/2 cup Mexican blend cheese, and green enchilada sauce.
Pour the chicken mixture into the greased casserole dish and spread evenly.
Pour the cornbread batter evenly over the top of the chicken mixture.
Bake for 25 minutes. Then add the remaining Monterey Jack and Mexican blend cheeses.
Continue baking for another 15 minutes until the cheese begins to brown.
Allow to cool and enjoy! Optional toppings: sour cream, cilanto, salsa, and avocado.
