Sweet and salty, gyudon is thinly sliced beef cooked with softened onion slices in a mixture of dashi, sake, mirin and soy sauce, and served over rice. We like to add eggs and scallions.
A party dish to make everyone gasp with delight! It looks pretty fancy, I know, but if you feel it's too much work to prepare lasagna this way, know that all the preparation can be done a day ahead.
