Sumashijiru (Clear Soup) with Komatsuna and Onion
すまし汁(小松菜・玉ねぎ) · Sumashijiru
By Aoi, licensed nutritionist · From a Japanese preschool lunch menu
Sumashijiru is the clear soup of Japanese home and school cooking: dashi seasoned lightly with soy sauce and a pinch of salt, so the flavor of the stock and vegetables comes through. Here it carries thin slices of onion, simmered until soft and sweet, and short pieces of komatsuna, a mild Japanese leafy green (spinach or bok choy leaves make a fine substitute). In preschool kitchens we blanch the greens separately and stir them in just before serving, so they keep their bright color and don't turn bitter or muddy the broth. Cutting everything small makes it easy for little ones to scoop up with a spoon.
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

Values are per serving (1.5× the Japanese preschool portion); an adult serving is double. They were calculated by a licensed Japanese nutritionist using the Standard Tables of Food Composition in Japan. "Salt equivalent" is sodium × 2.54, the standard Japanese measure. Allergen flags cover egg, milk and wheat only and come from the nutritionist's records. Soy sauce and miso are made with wheat but are usually allowed on Japanese wheat-free school menus, so check with your doctor.
