For those of you who carry foods in the trunks of your cars....whatcha got?

I'm not as keen to carry water (a.k.a. ice this time of year), and several mostly water items make the food nearly inedible in a pinch.

Still have a mess of bars of various types and some other stuff, but looking for some ideas. I eat out of mine on a regular basis and replace immediately.
