Chinese-Style Wakame and Potato Soup
中華スープ(わかめ・じゃがいも)
By Aoi, licensed nutritionist · From a Japanese preschool lunch menu
This is a simple, clear soup built on Chinese-style chicken stock, with tender strips of potato and finely chopped wakame seaweed. In Japanese school lunches, a soup like this often rounds out a meal with a stir-fry or rice dish, and children like it because the potato turns soft and gently sweet in the broth. The wakame is chopped small so it is easy for toddlers to manage on a spoon, and the seasoning stays light so the natural flavors come through.
