My wife and I love Brussels sprouts and this is our favorite way to prepare them. It's our own creation and so good that I'm amazed I have never seen a similar recipe anywhere. The flavors of the sprouts and the soy sauce seem made for each other. The recipe is quick and so simple that it can be thrown together as a side vegetable any time sprouts are on hand. I always use Tamari soy sauce, but anything you have on hand will do fine. And I always use olive oil, but butter or another vegetable oil would be fine if you prefer.
