I begin every day with this spirulina smoothie. Spirulina is a protein and iron rich blue-green algae that gives me a natural filling boost. I add it to a smoothie just like adding protein powder. Frozen blueberries help chill the drink without diluting it; if you want to use fresh blueberries, just add a few more ice cubes. This is also a great mellow out, post workout drink...especially if you enhance it with a little CannaOil!
