Tomorrow is our Halloween potluck for work and I still have zero idea about what I'm going to bring.

I think it's rude to not bring something, so I will be bringing a dish. I should mention that I'm not much of a cook when it comes to making huge portions or anything from scratch. I can make a really good frozen pizza, PB&J and cereal. I don't think that's going to cut it for my co-workers.

Yes, I could bring chips but I think someone else already has dibs on that. My questions is this--Is it OK to experiment with your cooking on your co-workers? It could taste awful and there's always a chance that it could turn out horribly wrong. I need some help and friendly advice.
