Place the yogurt, coconut water, banana, pineapple, mango, and spinach in a blender.
Turn the machine on low to begin chopping the ingredients, then slowly turn the speed up to high and puree until the spinach is completely smooth, approximately 1-2 minutes.
Taste; adjust ingredients to taste if desired.
Notes
To save time, I like purchasing pre-chopped pineapple and mango.
