GLUTEN FREE: Substitute barley, lentils, or cooked quinoa for pasta, and ensure your beef broth and sausage (if using) are gluten free.
VEGETARIAN: Omit meat and substitute vegetable broth for beef broth.
TO FREEZE: This soup freezes very well. Just leave out the noodles and add them in when reheating the soup to serve or they will get a bit soggy.
