Dude, my years eating int he dining hall were some of the best years of eating I've had in my life.
I don't know about your school, but they always had fresh vegetables, hard boiled eggs, whole grain breads, whole wheat pastas, fresh fruit... the works.
You should easily be able to eat fine.
Ha, I remember that I easily got 20-30 eggs a day thanks to my chow hall (No Yolk, of course).
