You can eat the seeds

Harvesting happens just before monsoon season.

Pick them when the pod is green and the seed tender. Eat them like you would peas or edamame. They've been know to be a little sweet.

You can also wait to harvest them until the seed is fully developed and the pod is dry. At this stage they're best eaten sprouted.
