Beyond the Red Bulls and cheap Domino's pizza: what are your good, cheap, quick recipes that can be easily-made ahead and downed straight out of the fridge, which will provide enough nutrition to get through all-nighters and exams week?

I'm currently running on energy drinks, string cheese and Chinese take-out (and procrastinating on studying for my 9am final by posting this).

Suggestions and recipes will be greatly and tired-ly appreciated.
