It may not be what your grandma made you when you were sick, but this chicken soup is just as nourishing --and it's guaranteed to ward off the chills (either from the flu or the outside temperature). Leek, potato, and carrot (a most classic trio) are the flavor builders, while giblets give the soup even more depth. Rather than more traditional pasta shapes, this soup features couscous, so you'll need to keep stirring during cooking to keep them from floating to the bottom.
