I'm looking for an appetizer -- maybe even more of an amuse bouche -- to kick off an elegant autumn dinner party. It's for a lot of people who head south for the winter, so I'd like to give them a taste of some cold weather food before they go. The main course is Pork Diane.
The catch is I only have so many burners and so much oven space, so the appetizer has to be served cold. Can you chowhounds think of something that would work? It can have an infinite amount of prep time, just as long as it goes out cold. Ideally it would have a nice presentation and be cocktail-hour friendly (ie, finger food), but I am open to all suggestions.
I've been kicking around the idea of a ham, apple and blue cheese skewer (sort of an autumnal twist on the classic melon and proscuitto) but I'm worried that will be too much like the main course.
