Tom Kha Gai means "soup coconut chicken" in Thai. This boasts traditional Thai flavors, but with lots of vegetables rather than mushrooms. If you like mushrooms, add them in! I've found asparagus, cabbage, and green beans are really good in this soup. If you don't use the bouillon I recommend, or sub a vegetable broth, you will probably need to add a bit more sea salt to make up for the flavor. Feel free to use fish sauce to flavor as well, although I prefer not to. If possible, make this soup the day before serving. We enjoy it on the first day, but all the flavors really develop after it sits a while.
