When my kids were in elementary school, I packed their lunches. I would include sandwiches and fruit and then they would buy milk in the cafeteria. I cut their sandwiches in odd shapes and they would put the sandwiches back together before they ate them. The other kids at their lunch table were always trying to get their sandwiches because they were more fun to eat. My kids called them puzzle sandwiches..pretty soon the other kids at the lunch table were showing up with their own puzzle sandwiches too!!
