2 cups chicken, shredded
2 cups cheese, shredded
1 can cream of chicken soup
1 can Rotel tomatoes
½ cup sour cream
½ cup milk
½ package taco seasoning (or more if you'd like)
Preheat your oven to 350°F. Spray a 2 quart casserole dish with nonstick spray. Mix together all ingredients except 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.
