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!

I made some alterations based on what I had. Used part leftover chicken and part canned, canned mushrooms, no jalepenos since a little one was eating it, no cream so I whisked a tbsp of mayo with about 3 tbsp of milk, 1/2 jar of pimentos, and preminced garlic.
This stuff is awesome for cold snowy days!!

This recipe was excellent. I didn't add any peas because I don't like peas. This recipe made two decent size dishes so I froze one of them. I also didn't have any spaghetti noodles so I used penne. My family loved this. I was skeptical about the jalapeno because I don't care for spicy foods, and it was not spicy in the least. I would actually consider adding another diced jalapeno the next time I make this.
