NBR: tailgating food

JLPT830

I'm taking DH to the Bengal's game this weekend for his bday and friends have invited us to tailgate with them.  They aren't sure if they will have their generator there.  I'm trying to come up with some food to bring to share that wouldn't need to be served warm in case I can't plug anything in.  Any ideas???  We aren't afraid of a little spice either.  :-)
