I like that this uses chicken instead of beef like most Doritos casseroles.
As a person who is not a fan of sour cream, this recipe was delicious. I think I am going to use a family sized bag of Doritos next time however. Needed a bit more crunch. Found this over at Plain Chicken. It was one of the meals we tested as a freezer meal and all that needed to be added before putting it in the oven was the crunched Doritos and the sour cream. Turned out great.
In the comments: have you ever tried freezing a recipe with sour cream in it? Did it keep well?
