Whether you or one of your family members is a vegetarian or not, you may want to switch to vegetable broth once in awhile instead of always using chicken broth. The vegetable broth gives this soup a real nice, deep vegetable flavor.
You may want to try another vegetable broth trick that I've learned. The next time you make a batch of rice, use vegetable broth instead of water. The flavor is quite nice and you get all the nutrients of the vegetables right there in your rice. Very cool.
