How about the Peach Bellini Recipe???
I found this one by Ina Garten online...
Ingredients
2 ripe peaches, seeded and diced 
1 tablespoon freshly squeezed lemon juice 
1 teaspoon sugar 
1 bottle chilled prosecco sparkling wine 
Directions
Place the peaches, lemon juice, and sugar in the bowl of a food processor fitted with a steel blade and process until smooth. 
Press the mixture through a sieve and discard the peach solids in the sieve. 
Place 2 tablespoons of the peach puree into each Champagne glass and fill with cold prosecco. 
Serve immediately.
