Well, since you've been here a while, I'm sure you've seen sarbar's site for freezer bag recepies at http://www.freezerbagcooking.com/ - but between that and most of my backpaking meals are just made with boiling water.

Now there's the trick - you're probably not allowed to fire off a backpacking stove in the dorm, but you can probably have a kettle, or sneak in an Electric Immersion Heater Speaking from experience, I don't get away with a backpacking stove, or a kettle in a university office or dorm, but I get away with an immersion heater.

Once you can boil water you an have a pot and a cozy, and get pretty creative.
