I remember those days well--mostly because I just got out of them! I moved into a house because I hated living in the dorm and having to rely on the school to feed me. You are definitely at their mercy when it comes to food choices. I was lucky enough that my school does have a cafeteria, but the endless supply of pizza and pasta and tacos calls much more frequently than the wilted salad bar. Besides that there is the Quiznos, Chickfila, Taco Bell, and Pizza Hut that is in the student center! It's all very frustrating. The good news is that you have a kitchen!

I love AllRecipes(.com). They have a section called Campus Cooking (I just found it--but I wish I'd found it a year ago). But kitchen aside, I eat a lot of light soups, especially for lunch. Also, I don't know what the rules in your dorm are, but consider investing in a crockpot--you can find lots of healthy recipes on the web for them. The crockpot is definitely a timesaver for me--I love having to do minimal work for excellent dinners!
Hope this helps!
