One doesn't want to wade too deep into canape land, but I would feel I was doing less than my duty if I didn't faithfully report my other most-relied-upon-starter-stand-in: beans wrapped in prosciutto. I saw these little bundles of green beans tied around the middle with Parma ham in an Italian delicatessen and went straight back home and made my own.
Top and tail some green beans and cook them in boiling salted water. Remember that the beans need decent cooking, not mere dunking in hot water. Drain them, wait for them to cool, dip them in balsamic vinegar, then cut raggedy thin slices of Parma ham in strips and tie them round the bean-bundles.
