My mom made this and I don't know where she got it from but it's all from memory. Its pretty easy to make, the longest part of the prep is cooking the pasta. Campbell's cheddar soup is the best and lower sodium content soups don't change the flavor. I have also used canned chicken which also tastes great with the recipe. My sister has also used other cream soups like cream of broccoli and cream of celery which give it a different flavor, but I prefer cream of mushroom.
