Really Chocolate Peppermint Smoothie

From Green Smoothie Girl's Judi Sears

Here's another one from the class I attended that tasted like dessert.

1-1/2 c. water (or coconut water)
1 banana
2 Tbsp. raw cacao powder
1-2 dates, soaked
1/4 c. walnuts
Handful fresh spinach
1/2 tsp. vanilla
1-3 drops doTERRA Peppermint Essential Oil
Ice cubes

Blend greens and water in high powered blender for 30-60 seconds.
Add remaining ingredients and essential oils to the blender and blend for 30-60 seconds, or until smooth.
