Green beans, also known as snap beans because they “snap” when broken, are harvested when young, when the beans inside the pod are small and tender and the pods are thin. They are very low in calories and loaded with vitamins K, A, and C, fiber, folate and anti-oxidants. Interestingly, green beans were originally cultivated in Peru and were then spread throughout Central and South America by Indian tribes. Spanish explorers brought them back from the “New World” to Europe in the 16th century, and from there they spread around the world.
