I heat the oven to 375°F and lightly grease a 9-by-13-inch baking dish.
I mix the chicken, beans, corn, chiles, cumin, and salt in a bowl.
I spread a little sauce in the dish, then layer tortilla strips, chicken mixture, sauce, and cheese. I repeat the layers and finish with cheese.
I cover the dish with foil and bake for 20 minutes. I remove the foil and bake for 10 more minutes, until the cheese melts and the edges bubble.
I let it rest for five minutes before serving, mainly so nobody burns their tongue while announcing they are starving.
