I love cabbage rolls, whether rolled or deconstructed, but regular sized ones are a bit too large and sloppy in my mind to put into all but the largest bento boxes. These are little bento sized cabbage rolls, just a bit bigger than a ping-pong ball. They aren't too showy to look at, but are deliciously juicy hot or cold. They are kept compact and slim by using napa or Chinese cabbage instead of regular cabbage leaves, since napa cabbage leaves are thinner and more tender, and using the smaller inner leaves that are about 10 inches (25cm) long.
Another feature of these mini cabbage rolls is that I tried making them in a rice cooker, and they came out great. I've also given instructions for making them on the stovetop, but if you're looking for more ways to utilize your rice cooker, you may want to try it out that way.
