When I am in Bologna for university I live alone, meaning that before I can eat I need to cook my meal, and before I can cook my meal I need to clean the kitchen. I am sure you'd be too lazy to eat too, in these conditions...
I tend to just get mayo, mustard, bbq sauce, etc and eat it with plain bread. Or cookies. In Aus right now there's these Anzac cookies, around 20 cookies for just 3 dollars.
