Simmered Soybean Hamburg Steak
煮込み大豆ハンバーグ · Nikomi Daizu Hambagu
By Aoi, licensed nutritionist · From a Japanese preschool lunch menu
Hamburg steak is a favorite on almost every Japanese school lunch menu, and this version stretches the ground pork with chopped boiled soybeans for extra protein and fiber. Soy milk and potato starch bind the mixture instead of egg and milk, so the patties stay tender without a dairy or egg binder. Baking the patties in the oven and then simmering them briefly in a ketchup and chuno sauce gravy keeps them moist and easy for little mouths to chew, and the sweet, tangy sauce is one kids happily mop up with rice.

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.
