Bok Choy with Natto
チンゲン菜の納豆和え · Chingensai no Natto-ae
By Aoi, licensed nutritionist · From a Japanese preschool lunch menu
This is a quick aemono, a Japanese dressed-vegetable side: blanched bok choy and thin strips of carrot tossed with natto, katsuobushi and a little soy sauce. Hikiwari natto is natto made from soybeans that are chopped before fermenting, so the pieces are small and coat the vegetables evenly, making it easier for little ones to eat than whole beans. The savory bonito flakes and soy sauce soften natto's distinctive flavor, and the sticky dressing helps the greens go down easily, so even children who are unsure about leafy vegetables tend to give this one a try.
Wheat-free, but uses soy sauce (made with wheat). Japanese school-lunch allergy menus usually allow it, so check with your doctor. How to read the labels
