I don't care for cooking on my own too much and do not frequently cook just for myself, but I really enjoy doing it as a shared experience with friends. Not cooking for other people (I am not a good enough cook to be confident about that too much), but doing it together. So, for me, it's not that I would invite friends for dinner etc, but for the whole procedure, including the necessary shopping. I agree it can be a very creative endeavor and allow for a better diet.
