For some reason, I'm really out of ideas here. I need some easy, relatively inexpensive hors d'oeuvres for an arts event with which I'm involved. The munchies should be individual, finger-type foods - not dips, for instance - that can be served cold or at room temperature. There will be a bar serving beer, wine and soft drinks. There will be several of us preparing the food - but I just can't seem to get beyond tortilla roll-ups. We'll also definitely have a raw vegetable platter and cheese and cracker tray. What else?
