You will need::
1 bag Nacho Doritos, crushed.
2C shredded chicken
2C shredded cheese--or more (I always use more!!)
1 Can Cream of chicken soup
1 Can ro'tel tomatoes
1/2C sour cream
1/2 package taco seasoning (or more if you'd like)
Preheat your oven to 350. Spray a 2 quart casserole dish with nonstick spray.
Mix together all ingredients BUT Doritos.
Layer half the Doritos (about 2 cups) on the bottom, then spread half the chicken mixture, rest of the Doritos, and the rest of the chicken mixture. Add more cheese on top.
Cover with foil and bake for 35 minutes.
I usually double the recipe and cook it in a 9x13 pan for 45 minutes, just so we can have leftovers the next day.
