In a high speed blender, combine the frozen zucchini coins with the avocado, peppermint extract and 1 1/3 cups of water. Blend well until smooth
Once the zucchini mixture is smooth, add the protein powder and addition 1/3 cup of water. This water may not be needed with a whey or paleo protein powder. Blend well until smooth
Add 1 tbsp cacao nibs and blend 5 seconds, just long enough to break up the nibs and incorporate them.
Serve cold
Notes
If you do not want to use a sweetened vegan protein powder, you could also use 1/2 -1 cup of Greek yogurt (regular or dairy free) + 1-2 tablespoons of your favorite sweetener (honey, maple syrup, low carb syrup) or 1-2 dates to sweeten this shake. NOTE: you likely will not need as much water as stated without the protein powder. If you do not have frozen spinach, you could also use 1-2 cups of frozen cauliflower rice or frozen zucchini in place of the spinach.Store in the fridge up to 24 hours in a sealed container.
