This is my new favourite. I know, I know, I've probably said that before but it is! It's perfect for special occasions because most of us either a) have a fussy friend who can't eat anything or b) are the fussy friend themselves. I come under category b) which annoys me because I don't like being fussy. I've had to learn the art of saying 'no' when offered delicious looking (chocolate) foods that I know will punish me later.
It's not like I don't eat gluten or dairy such to annoy people on a daily basis. Most people are the same with whatever food they avoid - usually there is a good reason and would love to be able to eat chocolate cheesecake and pizza. My reason: I eat gluten or dairy and don't feel so hot afterwards.
