Miso Soup with Tofu, Wakame and Onion
みそ汁(豆腐・わかめ・玉ねぎ) · Miso Shiru
By Aoi, licensed nutritionist · From a Japanese preschool lunch menu
Miso soup is the everyday soup of Japan, and this tofu, wakame and onion version is one of the most familiar combinations at the school lunch table. Simmering the onion until it is soft brings out its natural sweetness, so the soup stays mild and gentle even with a light hand on the miso. Soft cubes of silken tofu and finely chopped wakame are easy for little ones to eat with a spoon, and the miso goes in at the very end so it keeps its flavor and aroma.
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
