Nuts and Flax Protein Shake Posted on June 6, 2012 by CaFe Great taste in this Nuts and Flax Protein Shake. I used cashews, walnuts and almonds but you can mix your favorite nuts. I also used 1/2 cup of Almond milk and 1/2 cup of water and 1 scoop of protein shake (I use Lean Shake from GNC).Related PostsDay 59
