If you like soups as a main dish, this is a great one... hearty and filling. For a more traditional Tom Kha Gai, leave out the bok choy, tomatoes, and bean thread noodles, and add some extra mushrooms. But believe me, this soup is incredible as written. I can never find the galagnal traditionally used in Tom Kha Gai, but if you can get it, I say use some.
