what to pack for travelers

My German cousins are leaving to return to their home in Germany Wednesday and I want to pack them a nice care package so they won't have to spend their money on high-priced food in the airport.

Child, age 6, mom and dad.

German people who are probably becoming quite homesick but still loved a lot of the American foods they enjoyed here.

I already thought I should freeze some water bottles for them, and crackers/german bologna and swiss or gouda cheese, cucumber (the little girl's favorite), peanut butter and jelly sandwiches, granola bars, hard boiled eggs.

But what else should go?

I'd love your ideas.

Thanks!
