Sumashijiru (Clear Soup with Bok Choy and Onion)
すまし汁(チンゲン菜・玉ねぎ) · Sumashijiru
By Aoi, licensed nutritionist · From a Japanese preschool lunch menu
Sumashijiru is a clear Japanese soup built on dashi and seasoned with just a little soy sauce and salt, so the broth stays delicate and lets the vegetables shine. Here, thinly sliced onion simmers until sweet, and bok choy goes in right at the end so it keeps its bright color and soft bite. It is a simple, soothing soup that pairs easily with rice and a main dish, which is why it appears so often on preschool lunch trays. Made without egg or dairy.
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
