Do you seriously mean a total of 500 calories per day? I sincerely hope not!
Protein is actually less important while on a bulk when compared to a cut. In a hypocaloric state, protein needs increase due to the lack of fuel (calories) and increased desire/need to retain as much LBM as possible.
In a hypercaloric state, you still need protein but not as much. It becomes less important due to the excess of energy. Your body becomes more anabolic in general on a bulk.
I would focus on getting about 1-1.5 grams of protein per lb of bodyweight, unless you overweight by a lot. If that is the case, stick with 1-1.5 grams per lb of LBM.
All this protein talk aside, calories in vs. calories out is most important and right now we need to figure out if you really mean 500 calories total before we move on to anything else.
Lastly, don't resort to eating "crap food" just to reach your calorie goals! I think the best bet is to answer my above question as well as post a sample diet. Remember, I was a student once with 2 majors and a job with an active social life. My diet was still zoned in (minus the booze) and I was reaching my physique goals.
