I normally take whey by itself with water, but my girlfriend has got me into drinking green smoothies the last month, and I'm now blending whey into a post workout green smoothie, and it seems to be working out quite well. Smoothie: half cucumber, 2 celery stalks, 3 Kale leaves, 1 green apple, slice of lemon, slice of ginger, 1.25 cups water, 1.5 scoops vanilla ON protein. Blend in Blendec until smooth.
