I used boiled chicken that I cut in to cubes because I changed my mind on what I was cooking after boiling the chicken. It worked fine. You could also cook the chicken in a skillet with some seasoning. Cook until done. Stir in remaining ingredients, bring to boil, stirring constantly. Cook for a few minutes.
Drain noodles, place in bowl and add chicken mixture. We had this with Parmesan biscuits and it was good. Next time I might add some garlic powder and possibly some butter to the sauce. This was very quick and easy to make.
