You want a roasted nut in the end? edamame, as Re-design pointed out, is a boiled and salted preperation of soybeans. Usually not-fully matured beans. You could TRY a recipe an arts-director I knew used to make. Take normal, fresh peas(not in the pod). Frozen has worked OK, but just not as good as fresh. Soak them overnight in a brine solution(aka salty water). Drain and rinse(all the salt you want is already inside the pea now :-). Toss the peas in a bowl, with a tablespoon or two of olive oil. Preheat the oven to 450F. Spread the peas out on a cookie sheet, one layer thick. a little moe room is better than tightly packed. Bake for 30-40 min. Good wen hot OR room temp as a snack. Also works well for chick-peas, which is why I think soynuts should work too. Finally, I like mine a little spicy, so while still hot, I sprinkle on a little cayenne pepper and toss.
