Smoothies

At Costco, I had a smoothie. It had spinach, pineapple and orange juice as a Vitamix sample. I just had spinach. Wow.
Right before reading '365 skinny smoothies', I came across 'Ultimate Juices and smoothies Encyclopaedia' which I like better for the combinations. 365 Skinny smoothies calls for ingredients which I dont have in my pantry - hemp milk, coconut water. A substitution can solve that but the smoothies that would make me get up and go fix one in a blender are far and few.
