Also you can make pasta and sauce, divide it into lunch size tupperware and bingo - you have on the go lunches that you can reheat really quickly!
I do the same thing. While I do sit in an AC office, I still think 4-5 hours is not going to do too much.

I would pack PBJ on whole wheat. Or, the Zone bar- which is soooooo yummy.
