Preheat your oven to 350°F (175°C).
In a large mixing bowl, combine shredded chicken, black beans, green chilies, half of the cheese, cumin, chili powder, and salt.
In another bowl, whisk together the cornmeal, baking powder, and chicken broth until smooth.
Layer the chicken mixture evenly in the bottom of a greased 9x13 inch baking dish.
Pour the cornmeal mixture evenly over the chicken layer, distributing it softly.
Sprinkle the remaining cheese on top of the cornmeal layer.
Cover the baking dish with aluminum foil and bake for 25 minutes.
Remove the foil and bake for an additional 15-20 minutes until the top is golden brown.
Let cool for 10 minutes before serving, garnished with chopped cilantro.
