Adapted from allrecipes.com
1/2 package spaghetti or angel hair pasta
1 can Rotel tomatoes & green chilis
1 can condensed cream of mushroom or cream of chicken soup
1/2 cup cream cheese
2 cups chopped cooked chicken breast
1/2 cup shredded cheese
salt and pepper to taste
Bring a large pot of lightly salted water to a boil. Add pasta and cook until al dente; drain and return to pot.
To the pasta add the diced tomatoes with green chili peppers, soup, cream cheese, chopped chicken, salt and pepper. Cook and stir over low heat until cheese is melted and mixture is heated through.
I have made this with leftover pasta noodles and cooked chicken. Mixed all the ingredients together and baked covered for 30-45 mins (until warmed through) on 350.
