I whipped this up last week when I was under the weather with a sinus infection/upper respiratory/fever thing. I had no appetite, but needed something warm and comforting, and this did the trick. (Oh, and my family didn't leave me any leftovers, either! Thanks a lot, guys!) I used frozen home-made chicken stock with chicken harvested from a small fryer, but in a pinch, canned broth and chicken might work, too. Any short pasta would be fine.
