Notes
Store: Refrigerate soup leftovers for 2 days. Soup can last for 3-4 days but I find pasta becomes too soggy after 2 days. You can also thin out the soup with more broth and spices as it will thicken with time.I don't recommend to freeze this soup because noodles will become mushy upon thawing.
