In a blender, add the peeled and sliced kiwis.

Blend until smooth to create a kiwi purée.

Strain the purée through a fine mesh strainer to remove seeds (optional).

In a cocktail shaker, combine 2 tablespoons of the kiwi purée, limoncello, fresh lime juice, and simple syrup.

Fill the shaker with ice and shake well until the mixture is chilled.

Fill a champagne flute or a wine glass about one-third full with the kiwi-limoncello mixture.

Slowly top off the glass with chilled Prosecco, pouring gently to preserve the bubbles.

Stir lightly to combine.

Garnish with a slice of kiwi and a lime wedge on the rim of the glass.

Serve immediately and enjoy your refreshing Kiwi Limoncello Prosecco.
