Wrap all the ingredients in foil, and just heat in the toaster oven. Season with mentsuyu sauce for a gently flavored dish.
My daughter is allergic to sesame, so I cooked this dish to replace her school meal (the school cafeteria version contains sesame oil).This is easy to cook and delicious, so give it a try!
This has a mild flavour, so serve with a cut lemon or yuzu pepper paste to sharpen the taste. Use other kinds of vegetables if you like.
