Kabocha Squash Gratin
かぼちゃのグラタン
By Aoi, licensed nutritionist · From a Japanese preschool lunch menu
This gratin takes naturally sweet kabocha squash, mashes it with a little butter, and bakes it under a quick, mild meat sauce made with ground pork and ketchup. Kabocha is one of the vegetables children take to most readily, and pairing its sweetness with the savory tomato sauce makes it disappear fast. There is no cheese or white sauce here, so it comes together with just a frying pan and an oven, and the squash goes in skin and all so nothing is wasted.

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.
