Soybeans are a vey tasty snack. I'd never had them fresh, boiled from the pod until we went to Japan this past summer.
....and they fix nitrogen.
I'd try peanuts but I'm pretty sure the squirrels would get them. And I don't think my growing season is long enough.
I've had soybeans that way a couple times - been out with friends at a Japanese place who would order them as an appetizer. I wasn't too fond of them but I can see the appeal.
