Preheat the grill on medium-high heat. Place the peaches and lemon face side down and allow to grill for 5 minutes.
Allow the peaches and lemon to cool down completely. Cut the peaches into a large dice.
Squeeze the juice from the grilled lemon into a bowl.
Put the grilled, diced peaches, grilled lemon juice, and the honey into a food processor. Blend until completely smooth.
With a sieve, slowly pour the ingredients through, discarding of any solids.
To serve, put 3 tablespoons of the mix into a Champagne/Prosecco glass and slowly fill with the cold prosecco. Garnish with a slice of grilled peach or lemon and serve immediately.
