Lunch A looks like potato, kimchee, bean sprout soup, and kimchi chigae over rice.
Lunch B looks like seasoned squid, meat and potato curry, kimchee, and soybean paste soup with rice.
Lunch C looks like sliced radish with egg, mandoo (dumpling), kimchee, Deukboki (rice cake dish), rice and fish cake udon soup.
Pictured above are typical school lunches given to Korean school aged children. As you can see, all of the lunch trays include rice, soup, kimchee, and a Korean main dish of some sort. The kids eat their lunches with metal chopsticks, which is unlike American children who primarily eat finger foods (sandwich, chicken nuggets, pizza) for lunch.
