As an alternative to traditional noodles in chicken noodle soup, the ravioli are more filling and pack extra flavor. Look for small ravioli in your grocer's refrigerated foods section or thaw frozen ravioli if that's all you can find. Canned chicken stock makes this a quick lunch or dinner as well.
Heat chicken stock in a soup pot to boiling; reduce heat and add carrot and celery.
Simmer until vegetables are soft - about 20 minutes.
Add ravioli and cook according to package directions -- usually about a 5 minute simmer.
Stir in cooked chicken, salt and pepper as desired and serve.
