Vegetable Soup with Komatsuna and Bacon
野菜スープ(小松菜・ベーコン)
By Aoi, licensed nutritionist · From a Japanese preschool lunch menu
This is a simple clear soup built on consommé, with slivers of carrot, small pieces of bacon and bright green komatsuna (Japanese mustard spinach). The bacon gives the broth a gentle savory depth without heavy seasoning, and the carrot is cut into thin strips so it turns soft enough for small children to chew easily. Komatsuna is a tender leafy green that cooks quickly and stays mild in flavor; if you can't find it, spinach or baby bok choy works well in its place. Blanching the greens separately keeps their color vivid, but on a busy day it's fine to simmer them right in the pot.

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.
