wheat free

I can't have wheat or dairy and only natural sugar. This makes going to potlucks and things difficult because I have very little in the way of easy to prepare foods that other people actually want. Any ideas?

Whilst looking for recipes in came across an interesting recipe for an alternate chocolate cake recipe made with olive oil and ground almonds. The recipe is both wheat free and dairy free, with the latter being of particular interest to me. I am also guessing that it would not be that difficult...
