Arrange the vegetables on a plate.

Arrange the meat slices on a plate.

In a large jug, combine the soy sauce, Mirin, Sake, water and caster sugar.

Heat a large, heavy-based pot over a single burner.

Add the onion to the pot and use chopsticks to separate the slices.

Add ¼ of the vegetables and a couple of slices of meat then pour in about ⅔ of the sauce.

Bring to a boil and then reduce to a gentle simmer.

Eat the contents when they are cooked to your liking, dipping the meat in the beaten egg before eating it.

Add more veges and meat to the pot and repeat.

If the sauce level gets too low, add extra sauce (you can add a little extra water as it cooks down so it's not too strong).
