A refreshing and umami-rich tomato sauce coats the pork and cabbage in this stir fry in a delicious way. You can eat a lot of rice with this.
I had some leftover canned tomatoes so I used them in this.
If the tough core part of the cabbage bothers you, chop it up finely. Crush the whole tomatoes while you mix the tomato sauce.
Enjoy Japanese food around the world.
