Mix all the ingredients in a bowl and flatten the meat into one square like in the picture. Cut into 2-3 cm squares.
Cook on the griddle with your favourite sauce, such as a Yakiniku Japanese BBQ sauce (not listed).
Cook each side of the meat, turning with a spatula so it doesn't burn. It's done when the sauce has mixed in.
You can also make this in a frying pan, and serve it with grated daikon radish and ponzu sauce. It is delicious.
Story Behind this Recipe
Diced steak is expensive, but I wanted to eat it! So I made diced steak using cheap ground beef!
I sometimes make "Garlic Steak Pilaf" with this recipe - add rice to the cooked diced steak and stir-fry with garlic, soy sauce and butter as you gently crush the rice and meat. It is also very delicious.
