Love those little bowls of miso soup at Japanese restaurants? Here’s your chance to make it at home. This version adds flavor and nutrition in the form of chicken, sweet potato, mushrooms, bok choy and soba noodles. Soba noodles are made with buckwheat flour and are a good source of B vitamins and phosphorus. The shiitake mushrooms add B vitamins, potassium and magnesium. The first time I ate a bowl of this soup, I could feel it working its magic on my ever stuffed-up sinuses. It’s a healing soup, that’s what it is. Winter blues got you down? Twirl some noodles on a fork. Chills and sniffles? Let the hot broth run down your throat. It’s happy time again.
