In a large pitcher, pour in the cranberry juice, prosecco or champagne and lime juice. Stir to combine. Pour into champange flutes or tall slender glasses and garnish with a few frozen cranberries in each glass. Served Chilled.
For the virgin version: Swap out the processo/champagne for 14 oz. of ginger ale and increase the amount of cranberry juice to 14 oz.
