I always want to be ready for a picnic, so I have outfitted a clear organizing cube.
Here's the exploded view along with a list of contents:
cutting board (cut down from one of those flexible cutting boards)
swiss army knife with serrated (for bread) and plain blade-- omitted for air travel
wine recorker- just in case that bottle doesn't get finished. Hey, it /could/ happen.
toothpicks in case
small container with salt, pepper and italian seasoning
disposable hand wipe
plastic utensils, bandana packed in Planetwise snack size bag
planet wise sandwich wrap- this makes a nice surface to spread out fruit, cheese and bread
