Mung beans are another type of shell bean. Mung beans are very popular in Asian cuisine. This is the type of bean that bean sprouts come from. It's cooked in different ways and eaten in India, China and other countries in Southeast Asia and the Far East. It's too bad that we don't eat more of this great shell bean.
Those who cook international dishes at home are familiar with this bean, but I don't think it's used in American cuisine at all. It's really nutritious and easy to cook with though. There are different varieties out there, but I mostly use the green variety.
