This style of eating has been adapted from Japanese tradition. It uses a lunch box that contains separate compartments. I'm sure you've seen these containers before. They're readily available at the grocery store these days. I have stainless steel bento boxes in two sizes: medium and large. I use both often for myself and my daughter. I'm using the bento box with three compartments in the photos. These boxes might seem like an investment at first. But they are way more durable than the plastic versions, which in my experience don't last very long. I started out with two plastic bento boxes, both of which broke after a few months (and cost me $7 each). That's why I ended up purchasing stainless steel ones. These have been with us for over five years now and will probably last our lifetime if we don't lose them.
