Sumashijiru (Clear Soup with Tofu and Wakame)
すまし汁(豆腐・わかめ) · Sumashijiru
By Aoi, licensed nutritionist · From a Japanese preschool lunch menu
Sumashijiru is the clear, dashi-based cousin of miso soup: instead of miso, it is seasoned with just a little soy sauce and salt, so the flavor of the stock shines through. This version pairs soft cubes of silken tofu with tender wakame seaweed and thinly sliced onion, which sweetens as it simmers and rounds out the broth. At preschool it turns up alongside all kinds of main dishes, and its mild taste and soft textures make it easy for even the youngest children to enjoy.
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

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.
