Bok Choy has more protein than almost any other green.  Last night when I got home from school I took a couple pieces of bok choy, a tomato, cucumber, a garlic clove, rainbow chard, a carrot, some aloe vera juice and water and put it in my bullet.  I made a nice thick soup that tasted like a garden salad.  It was wonderful and loaded with protein and nutrients and only took about three minutes to make.
