We're having trays of sandwiches at our reception, which is at a nonmeal time. Per the deli, each tray is 20 sandwiches, which feeds 20 people. The sandwiches are cut in half, so 40 pieces per tray.
We have 43 guests coming, 13 of which are kids under 10. Should I get two trays or 3? I'm thinking three trays would equal a lot of uneaten sandwiches, since the kids won't eat as much as an adult would. If the kids ate half a sandwich each and adults ate a whole, that would be 67 pieces needed, or two trays. We are serving other snack type foods as well: chips and dip, cheese and crackers, fruit, and cake.
