This first time I had these I was at a sushi restaurant and it was love at first taste. Edamame is soybeans. You can buy these in bulk if you like and they come separated in portion sizes. You just take them right out of the freezer and you can steam them in 5 min. Sprinkle them with salt and then slide the beans out with your teeth. Don't eat the whole thing. You just want the beans inside their shell and you suck them out.
You can cover them in anything you want. You can make a glaze that I blogged about previously. Of you just sprinkle with salt, or dip them in soy sauce or a dipping sauce for spring rolls. The options are endless. Soy is also a complete protein.
