Although it is served as a soup course in North American Thai restaurants, it actually falls somewhere between a soup and a curry. In Thailand, it is served as a condiment to rice, just like any of the other dishes on the table. In a medium-sized saucepan, bring stock to a boil and add mushrooms and chilies. Tie lemon grass and lime leaves or zest together in a cheesecloth bag and add to the stock mixture. Cook over medium heat for about 5 minutes, or until the mushrooms are tender. Reduce heat to low and add lime juice and fish sauce. Discard the cheesecloth bag. Serve the soup hot, accompanied by steamed rice. 43 CALORIES PER SERVING: 4 G PROTEIN, 1 G FAT, 7 G CARBOHY- DRATE; 397 MG
