One thing I have started to do is pack canned vegetables. I buy the smaller cans with pop-tops. Don't take up alot of space and stack real good. They are good for a late night snack. If the room does not have a microwave I use the coffee pot. Pop the top on the can. Heat some water with the pot into one of the styrofoam cups. Place the can into the hot water to heat the whole can. You might have to reheat the water once or twice but it works pretty good. I'm told this also works for spaghetti-o's and ravioli's.
