How to Make It
Preheat broiler to high.
Lightly coat bread slices with cooking spray; broil 2 minutes on each side or until toasted. Combine mascarpone and next 3 ingredients (through cream cheese) in a small bowl. Stir in 1 tablespoon basil. Spread cheese mixture evenly among bread slices.
Wrap each peach wedge with 1 prosciutto piece. Top each bread slice with 1 wrapped peach wedge. Sprinkle with remaining 1 1/2 teaspoons basil. Serve immediately.
