Soybean Menchi Katsu (Japanese Minced Meat Cutlet)
大豆のメンチカツ(卵なし) · Daizu no Menchi Katsu
By Aoi, licensed nutritionist · From a Japanese preschool lunch menu
Menchi katsu is a Japanese favorite: a seasoned ground meat patty coated in panko and deep-fried until golden, the kind of thing you find at butcher shops and in bento boxes all over Japan. In this preschool version, roughly chopped soybeans are mixed into the pork, which stretches the meat, adds a gentle nutty sweetness, and slips extra beans into kids who would never eat them plain. Instead of the usual egg, a simple flour-and-water batter holds the panko in place, so the cutlet is made without egg and still has the same crunchy coating. Skim milk powder dissolved in warm water keeps the mixture moist and tender without adding any strong flavor.

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.
