Vegetable Soup with Komatsuna and Onion

野菜スープ(小松菜・玉ねぎ)

By Aoi, licensed nutritionist · From a Japanese preschool lunch menu

This is a simple clear soup from the preschool kitchen: sweet onion simmered gently in consommé broth, finished with tender komatsuna (Japanese mustard spinach, a mild leafy green - regular spinach works as a substitute). Slow-cooking the onion over low heat draws out its natural sweetness, which is what makes children happily drink up their soup. The komatsuna is boiled separately and stirred in at the end so it keeps its bright green color and soft, easy-to-chew texture.

Directions

  1. 1

    Cut the komatsuna into 2 cm pieces and boil in hot water for 5 minutes. (Boiling it separately keeps the color bright, but if that is too much trouble, it is fine to simmer it together with the soup.)

  2. 2

    Cut the onion in half lengthwise, then into thin slices.

  3. 3

    Put the water, the onion from step 2 and the consommé bouillon in a pot and simmer over low heat for about 15 minutes.

  4. 4

    Once the onion is soft, adjust the seasoning with salt, then add the komatsuna from step 1 and stir it in.

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.
