Recipe by Kittencal@recipezazz

Three flavors of canned soup takes the place of a creamed sauce for this recipe, I like to use 2 cans cream of mushroom and 1 can cream of chicken, I would suggest to add in salt if needed at the table as the creamed soups have enough salt already added . This is really good! :)

This was very good and extra rich! My personal opinion was that it was too thick for me, and perhaps next time I will use milk instead of the cream to make it less heavy and thick. I used a bit less noodles so that it would be slightly more saucy and it was perfect. I might also add chopped celery as I think this will add more flavor and texture. Thanks!
