1) Add all ingredients to a high-powered blender in the order listed and blend for a few minutes until smooth. If the consistency is too thick to blend, add a bit more juice. Don't add too much because the ingredients become thinner after it blends for a few minutes. If you want it thicker, add more frozen fruit (rather than ice). This recipe makes 3 1/2 cups with the yogurt and 3 cups without the yogurt.
