I'm having a dinner party with a somewhat Italian flair - some kind of salad in parmesan cups, Giada's balsamic chicken, some kind of polenta, a simple green veggie and panna cotta for dessert. Still some details to be worked out. But I want to serve some hors d'oeuvres before dinner. Nothing too filling, and on the elegance scale somewhere between chips with dip and blini with caviar and creme fraiche. Any suggestions? Thanks!
