Living away from anything really convenient when drinking, if you stay past the time the kitchen closes, I've become somewhat of a frozen pizza guru. Anybrand will do, you just have to load it up with whatever is handy. Cheese of course, any type of luncheon meat, spam, veggies if they seem like a good idea at the time, but completely unecessary.
I got this tradition from my father who would do the same, and sometimes even wake me up to help partake.

The only thing that really didn't ever work was baked beans. But if you just use those, cold as a dip with potato chips, no need to put them on your drunk pizza.
