I'm sure that more people then me have had this "problem". You have been doing something for too long and lost track of time or you have been working longer than usual and just got home and it's almost time to raid and you need to eat something. Only problem is there is nothing in the fridge or freezer. This keeps happening to me and I'm starting get tired of my solution.
My emergency food is usually a tuna sandwich. It's fast to throw together and it usually doesn't mess up my keyboard when I eat at my comp.
What is your "oh crap I need to eat before the raid" food?
