Miso Soup with Komatsuna and Potato
みそ汁(小松菜・じゃがいも) · Miso Shiru (Komatsuna, Jagaimo)
By Aoi, licensed nutritionist · From a Japanese preschool lunch menu
Miso soup is on the table at almost every Japanese preschool lunch, and the vegetables in it change with the season and the menu. This version pairs komatsuna, a mild Japanese mustard green (baby spinach or bok choy leaves work as a substitute), with potato simmered until it is soft enough to break apart on a spoon. The potato gives the broth a mellow sweetness, so even children who are wary of greens tend to drink the whole bowl. Blanching the komatsuna separately and adding it right before serving keeps its color bright and its texture tender rather than stringy.

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.
