Thai Fish Soup Recipe

Recipe adapted from The Medicinal Chef: Eat Your Way to Better Health by Dale Pinnock.
Make this healthy soup a perfect light meal by adding 1/2 pound of dried rice noodles (cook the rice noodles according to package directions).
You'll season to taste with the balance of fish sauce and lime juice. Adjust with more if needed, for more intense flavor.
If you cannot find lemongrass or kaffir lime leaves, just substitute with the peel of a lemon or lime. Use a vegetable peeler to get thin strips of peel (avoid the bitter white pith) and give each strip a good bruising or twist to release the oils).
The last time we made this soup, we added fresh tomato cut into wedges too - I highly recommend that you do the same!
