This refreshing smoothie is one of my favorites for summer. Fresh peach and mint are such a great flavor combination. During the summer, I buy extra peaches each week and wait for them to get almost too ripe before transferring them to the refrigerator - this way I have them always ready for this smoothie. Note: while fresh nectarines work well, frozen peaches do not. They just don't have enough flavor to make this tasty.
Place ingredients in a blender and blend until smooth.
