Actually, I found it easy to eat in college. I used to bring tiny tupperware things in a backpack. The lunch ladies always had tuna around..and we always had pasta too. A couple of scoops of pasta covered with a can of tuna makes a pretty good quick meal.
I used to swipe hard boiled eggs all the time...milk went into a thermos...you name it...I took it.
You know...pizza can be eaten on juice if you are trying to bulk. Just remember to also get your protein and target caloric range everyday.
