Miso Soup with Kabocha and Komatsuna
みそ汁(かぼちゃ・小松菜) · Miso Shiru (Kabocha, Komatsuna)
By Aoi, licensed nutritionist · From a Japanese preschool lunch menu
Miso soup is on the table at nearly every Japanese school lunch, and the vegetables in it change with the season. This version pairs kabocha squash, which turns sweet and creamy as it simmers in dashi, with komatsuna, a mild Japanese leafy green (spinach or bok choy leaves work as a substitute). The natural sweetness of the squash softens the saltiness of the miso, so even children who are cautious about greens tend to drink it all up. Blanching the komatsuna separately keeps its color bright and fresh-looking in the bowl, but on a busy day it is perfectly fine to simmer it with the squash.
Wheat-free, but uses miso (made with wheat). Japanese school-lunch allergy menus usually allow it, so check with your doctor. How to read the labels
