Green smoothies are what I make when I am in a rush. They aren't always green in color but they are always loaded with a ton of greens such as kale and spinach. My base is usually water but sometimes I'll do coconut water or almond milk. If I want something chocolately (that should so be a word), I add a scoop of chocolate protein powder and then add a scoop of peanut or almond butter, a banana and a couple of handfuls of spinach and/or kale. If I want a fruity one, I'll do berry or vanilla protein powder, a variety of berries. Yes, you still throw in the greens! If you have a powerful blender like a Vitamix or a Blendtech, you can thrown in carrots and tomato. Just add more fruit if you don't like the flavor.
