The Sudanese eat one meal (usually a plate of fuul, which is beans) at about 10:00 AM, then the main meal at about 2:00 PM, then another little meal at about 10:00 PM.
Our school follows the Sudanese model, and gives us a break at 10:00 AM in which a lot of people eat food from home. Recently, however, they've been trying out providing school lunch. Different moms volunteered to cook easy foods for any kids who pre-ordered a month ago. This was what we got the week the Korean mom cooked... only there were about 10 pieces of sushi when I got it. I wanted to save more to make a nice photograph, but they were too good!
