Pairing the warm, sweet taste of nectarines with salty prosciutto makes a wonderful first course. It is even better when served with a glass of champagne.
If you can find them, try substituting fresh apricots.
Position your oven rack on the top shelf; preheat broiler. Quarter the nectarines (if using apricots, halve them) and remove the stones. Dip the cut side of each nectarine section (or apricot half) in some of the olive oil and place, cut side up, on a baking sheet.
Place fruit under broiler 3 to 5 minutes.
