Wonton cases baked in mini muffin tins. Make a batch of shredded chicken, avocado, spring onion and seeded diced tomato and seasoning, a squeeze of lemon to protect the avo. Put it in a container and when you get to your destination assemble. Same can be done with bruschetta mix and caprese stacks.

Also half pitted dates with Camembert or Brie wedge is amazing.
