Chinjao Rosu (Japanese Pepper and Pork Stir-Fry)
チンジャオロース · Chinjao Rosu
By Aoi, licensed nutritionist · From a Japanese preschool lunch menu
Chinjao rosu is the Japanese take on the Chinese stir-fry qingjiao rousi: thin strips of meat and green bell pepper tossed in a savory, glossy sauce. It is a staple of home-style Chinese cooking in Japan and a regular on school lunch menus. This preschool version swaps the usual bamboo shoots for potato, which is easier to find and gives the dish a gentle, familiar sweetness that helps little ones warm up to the green peppers. Everything is cut into slim matchsticks so it is easy to pick up and chew.
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

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.
