Cut the cucumber into 1 ½ inch pieces and hollow each piece of cucumber with a small scoop or small teaspoon. Place the remaining ingredients into a food processor and process until smooth. Place the mixture into a freezer bag and cut the end just a tiny bit so this becomes a piping bag for the mixture. Pipe the mixture into each hollowed cucumber round and garnish with some fresh chives. Chill and serve. Makes 6 servings.
