While teaching the 2013 "Cuisine Around The World" cooking elective at my daughter's charter school each 3rd-5th grade student created their own bento box and onigiri for our day in Japan. A bento is the Japanese version of our "brown bag" lunch. They're fun and easy to make, and kids can enjoy making their own lunches the night before. The ingredients list is just some ideas to get you started. The yield is for 3 cups of cooked rice. That amount made about 4 onigiri when we were figuring out how much rice we'd need for 30 students. My students really enjoyed getting creative with their bento and onigiri. The photos are actually some of my students' creations.
