A good-sized dutch oven or crock pot may prove very useful to you and your roommates. Speaking from experience, 3 hungry guys in the middle of January may appreciate hearty and inexpensive stews, potroasts, and all kinds of single-pot recipies. I would also recommend a roasting pan with a rack... it's tough to go wrong with roasted chicken, pork loin, or whatnot. Simple and delicious. Also, don't forget the good old Weber grill, if you have the space.
Red meat isn't bad for you. Fuzzy, green meat is a different story, however.
