Locally in Malaysia, rice vermicelli is fondly called ???Bihun??? or ???Beehoon??? or ???Meehoon???. It is usually dry and comes in thin and bundled together in a packet. It is inexpensive and easy to cook. Tom Yam on the other hand comes from 2 words : ???Tom??? means soup and ???Yam??? means spicy and sour salad. Together it means spicy and sour hot soup. Today tom yam is sold in convenient packaging in the form of paste. This is a simple stir fry rice vermicelli ( Mee Hoon ) with tom yam paste. This flavoured noodles is famous for its light, sweet yet savoury and sourish taste. Certainly very appealing for those who enjoy Thai food.
