½ cup roughly chopped English cucumber, plus one slice reserved for garnish
3 tablespoons lowfat buttermilk
1 tablespoon honey, optional
1/2 small lime, juiced (about 1 tablespoon)
2 cups cubed seedless watermelon, frozen
Put the cucumber, buttermilk, honey if using and lime juice into a blender. Blend on high until smooth. Add half of the frozen watermelon and blend until almost completely smooth, turning off the blender and pushing down on the ingredients with a spatula or wooden spoon as needed to help the blending process. Add the remaining frozen watermelon and continue to blend until smooth. Add 1 to 2 tablespoons of water if needed to adjust consistency. Pour into a glass and garnish with a cucumber slice.
