This Japanese cabbage and wheat pancake, also known as Japanese pizza, is both healthy and delicious. Any kind of cabbage can be used, although standard green cabbage is the most common. Other vegetables that can go into the pancake include shredded carrots, scallion, onion and mountain yam, which you may be able to find at your local Asian food store. Traditionally, bacon or pork belly is placed on the griddle before the pancake batter is added, so that it makes a rich topping when the pancake is flipped. I also like to add shrimp, scallops or salmon to the pancake batter.
