1. Place all ingredients into blender, and mix on high until completely smooth. This took less than a minute in my Vitamix, but may take a few minutes in a lower-powered blender.
2. Divide smoothie into 2 bowls, add desired toppings, and eat.
Notes
The thickness of these smoothie bowls comes mostly from the frozen fruit and avocado. If you use fresh fruit, expect a much thinner smoothie.
