Food photography and scanned sandwiches

Yesterday I stumbled on Chow's10 Ways to Photograph Food.  I like the idea, but I wish they had featured more than just apples.  Does anybody know of a good tutorial for photographing finished dishes?

While reading through this feature, I discovered Scanwich, which is more than just a clever name.  Yes, it's actually a collection of scanned images of sandwiches.  What can you infer about me by the fact that my first thought was, "Who has to clean the scanner each day?"

I also discovered  How's that for photography inspiration?
