Miso Soup with Tofu and Onion
みそ汁(豆腐・玉ねぎ) · Miso Shiru (Tofu, Tamanegi)
By Aoi, licensed nutritionist · From a Japanese preschool lunch menu
Miso soup is on the table at almost every Japanese meal, and this tofu-and-onion version is one of the simplest and most soothing. Simmering the onion in dashi until it turns soft and sweet gives the soup a natural sweetness that little ones love, while silken tofu adds a soft, tender bite that is easy for small mouths. In preschool kitchens we keep the miso light so the flavor of the dashi and vegetables comes through.
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

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.
