Preheat your oven to 375°.
In a large bowl, combine the chicken with cumin, coriander, cilantro, black beans, and green chili peppers. Mix it well.
Spread half of the enchilada sauce over the bottom of an 11x7 inch baking dish that has been sprayed with cooking spray.
Place 4 tortillas over the sauce, overlapping if necessary.
Spoon half of the chicken mixture over the tortillas, and sprinkle with half of the cheese.
Spread half of the sour cream over the layer.
Spoon the remaining enchilada sauce over the cheese and sour cream.
Make another layer of tortillas.
Layer the remaining chicken mixture over the tortillas.
Cover the dish with a lid or aluminum foil and bake for 30 minutes in the preheated oven.
Remove the cover, and sprinkle the remaining cheese over the top. Continue cooking, uncovered, for an additional 5 to 10 minutes, or until cheese melts.
Remove from oven and top with the remaining sour cream and cilantro. Let stand 10 minutes before serving.
