One thing to keep in mind when you're blending is that because this has virtually no liquid, it will be on the thick side. You may need to stop and scrape down the sides of your blender or add a little extra liquid to get the blades moving. If you have a high-speed blender it will probably have less trouble. The longer you blend, the thinner the smoothie will be so go easy on the liquid if you do decide to add a tiny bit more.
