My reply to Ed's frozen banana post made me start thinking about this again.
I grew up in a large family, so food and meals were about community as much as anything. I have some close friends (tight-knit and geographically) and we will sometimes have dinner together during the week. But usually I am on my own in the evening. And it's just hard to get inspired somehow.
Often I won't make my favorite meals because either it seems like too much hassle after work for just me, or because the recipes make way too much and I would end up eating it all week (or way too much at one meal because I love it!

Am I the only one who thinks a lot of the joy of cooking is missing when it's just for one?
