Preheat your oven to 400°F and lightly coat a 9x13 baking dish with cooking spray.
In a large mixing bowl, combine the creamed corn, corn muffin mix, green chiles, sour cream, egg, cumin, and 1/2 cup of cheese. Stir until just combined.
Pour the mixture into your prepared baking dish and bake for 20-25 minutes, or until the edges are golden brown and the center is set.
Once the cornbread base is done, use the back of a wooden spoon to create dents across the surface.
In a medium bowl, mix shredded chicken with the enchilada sauce. Spread this mixture evenly over the baked cornbread base.
Top with the remaining shredded cheese and return to the oven for another 5-10 minutes, until the cheese is melted and bubbly.
Remove from the oven and let the casserole cool slightly before slicing into squares.
Serve with your favorite toppings like sour cream, avocado, tomatoes, and cilantro. Enjoy!
