Green Peanut Butter Banana Smoothie

I started drinking this smoothie because I wanted something quick with some protein and no added sugar for breakfast.  It works really well with my Ninja using the 16 oz single serving blender jar.  Some people will think this is not sweet enough, so I say put in a whole banana if you don’t care how much sugar you are drinking.  Bananas are rad as a natural sweetener, but they have so much natural sugar that I only use 1/2 of a medium banana or 1/3 of a large banana in my smoothies.  It is a great way to use up all the frozen bananas I store when we don’t eat up every one in the bunch.  I also store leftover greens in the freezer and use those in this recipe too, only the volume will be a little off since the leaves compact when frozen.
