This Avocado Banana Smoothie is a healthy smoothie that has a great balance of being naturally sweetened with the banana and dates, however it has a slight earthy undertone from the avocado and spinach. I like to add a pinch of cardamom or cinnamon for a little sweet spice. The texture of this Avocado Banana Smoothie is thick and velvety, just right to me, but you be the judge!
