So you're stuck in the dorms with an anti-cooking nazi RA? Been there, faced with the same problem. I eventually made friends with two girls who lived off campus. In exchange for use of their kitchen facilities, I prepared them several meals a week - whatever I was cooking for myself. A side benefit (other than the obvious <img src="/forums/images/graemlins/wink.gif" alt="" />) was that sharing home-cooked food back at the dorm brought in a steady stream of consumables that I was not old enough to buy. <img src="/forums/images/graemlins/grin.gif" alt="" />

You could cheat on the refrigeration by acquiring a thermoelectric cooler - looks like an ice chest but can plug into the wall. Indoors it should easily keep things in the 40-degree F range. Depending on what size you get, it can be hidden during room inspections or placed in a vehicle.

Other than that - all I can suggest are MRE meal heaters. These come in a pouch that you fill with water. In seconds, the pouch is full of boiling-hot water. You're supposed to place your MRE inside, but any heat-and-eat food will work with these - even stuff in cans, like Chef Boyardee, Pork & Beans, etc.. I suppose you could even use frozen dinners if they're small enough, like the Stouffer's and Budget Gormet. Just thaw them before heating. The site I linked above is just one of many that sell these. Don't take my linking as an endorsement - never ordered anything from them.
