Bento Box with Tonkatsu as a main is called Tonkatsu Bento. It consists of cooked rice, tonkatsu and a small amount of a few side dishes. It is intended to be eaten at room temperature. I have written my instructions on how to pack the box to make it look like the photo of the bento box in the post. But you don’t need to place the ingredients in the same way.Because bento is usually made mostly from the left-over dishes or make-ahead dishes, the time indicated in this recipe only shows the time to pack the bento box.
