Put the water and greens in your blender and blend until smooth.
Add the fruit and blend to desired consistency. [Or for convenience like I said above, just put all the ingredients in a baggie and dump it all in the blender at once. If you have a high-powered blender (I use a Vitamix), you won't have a problem.]
Can also add any other fruits, nuts, seeds, veggies, protein powder, etc. that you'd like.
