Moringa pods are quite nutritious, and can be cooked in a variety of ways. They can be boiled, steamed, fried -- essentially, cooked any way that one might use green beans or asparagus.
The pods are best for eating when they are young and tender. When they are too old, they become woody and fibrous. A good test is to bend the pod -- if it snaps and breaks in half, it is good to eat. If it does not break, it is likely too old.
