I'm going into my second year of college and this is the cheapest way I have found to maintain this lifestyle while dorming, assuming that you can make a trip to the market once a week, you have a microwave, and a fridge:
oatmeal, whey, chicken, brown rice, whole eggs, almonds, Metabolic Drive bars
Get yourself a 15 dollar rice cooker and 15 dollar George Foreman Grill from somehwere like target. I plan on cooking up a week's amount of rice on sunday and storing them in containers. As far as chicken goes, I will just grill them when I am going to eat since it only takes about 5-10 minutes, and cleanup on the George Foreman takes less than 20 seconds.
I know I should be getting in more greens but whatever.
