Sandwich trays and boxed lunches

Boxed lunches provide the tightest count: order one for every attendee, including organizers and vendors, then separate vegetarian, vegan, allergy-aware, and other dietary meals. For shared sandwich trays, plan about one and a half standard sandwiches per adult when lunch is the main meal.

Confirm attendance close to the order deadline, label special meals, and keep a small reserve rather than rounding every item upward.
