Roasted beet pieces nestled among their sauteed greens makes a beautiful, delicious side dish. If yellow beets are available, double the recipe using a bunch of red and a bunch of yellow, they're gorgeous! I think these go especially well with pork or chicken. This recipe can easily be doubled, tripled, or expanded to whatever amount you need without adding very much to the preparation time.
You can use yellow, white, or red miso paste for the soup, depending on your preference. You will also need dashi, which is made of dried kelp (seaweed) and dried bonito (fish), and can be purchased in granules or powder form in conveniently-sized jars.
