In this weeks portion, one of the comments that is made about the 40 years' travel is how the cloths of the Israelites never wore out. Kind of like friendship. Or Shabbat.
"Dark Side of the Moon", "The Breakfast Club" and "Star Wars" (the first one. No not episode 1. The *real* first one, that I saw when I was 10) might also fall into that category, but I'm not sure.
So, limited only by your creativity and the category of food assigned, please bring a food which doesn't wear out.
