Assuming you have access to a refrigerater & microwave:
100% rolled oats
Whole grain bread
natural peanut butter
mixed nuts (walnuts, almonds, cashews, etc) - to complement amino acids
Canned tuna [Warning: limit your intake to avoid mercury poisoning in the long run]
MRPs - if you don't have time
None of the above requires any cooking beyond that of a microwave...
this is what i did / what i would have done back in college.
Ah...College...those were some good times.
