Bean there...ate that! In Vietnam, sweet soups or puddings are known as chè. This Vietnamese Mung Bean Dessert, called che dau xanh, is easily one of the most simple Vietnamese desserts to make. Mung beans are said to have cooling properties on the body and other health benefits, but I'm no doctor. To me, this is purely a yummy dessert that can be served hot, cold, or over crushed ice. All you need are 4 simple ingredients - mung beans, sugar, coconut milk, and water!
