You boil them for a couple of minutes (in salted water) and eat the beans for a snack.
I went through a whole bag of frozen soybeans yesterday afternoon.
Soybeans are a vey tasty snack. I'd never had them fresh, boiled from the pod until we went to Japan this past summer.
Ah...you'd eat 'em green, then, right?
I like those...let me know if you do grow 'em! If they're fairly easy, I'd like to try doing that. The frozen ones are awful pricey...
