This nonalcoholic mojito is perfect for St. Patrick's Day or anytime you'd like a refreshing drink. To make the garnish, cut a shamrock from a slice of cucumber skin using a shamrock cookie cutter.
Place lime, mint, cucumber slices, and sugar in a tumbler or highball glass and muddle. Add ice to glass; pour honeydew melon juice over ice. Top with club soda. Stir and serve immediately garnished with cucumber skin "shamrock."
