Easy quick meal. You can increase the heat by buying hotter enchilada sauce. Left overs are amazing and it freezes well - if you have any left!!. I make it in small containers and freeze one and eat one that night!
Preheat oven to 375 degrees. Grease a 13 x 9-in baking dish.
Mix the chicken, enchilada sauce, sour cream in a bowl.
Cut tortillas in to 1-1/2 inch strips.
Place enough tortilla pieces to cover the bottom of the baking dish. Cover with half the chicken mixture. Add more tortillas on top. Sprinkle with 1/3rd of the cheese. Layer with the remaining chicken mixture, tortillas and rest of cheese.
Cover and bake 40 minutes. Uncover; bake 10 minutes longer or until bubbly. Let stand 10 minutes before serving.
