I heat the oven to 350°F and grease a 9-by-13-inch baking dish.

I stir together the chicken, sour cream, soup, chiles, and salsa.

I layer tortillas, chicken mixture, and cheese twice in the dish.

I cover it with foil and bake for 25 minutes, then uncover and bake 10 minutes more.

I let it rest for 5 minutes before serving.
