Green smoothies are blended drinks that contain fresh leafy green vegetables in them, such as Kale, Collard greens, Swiss chard, Spinach, Mint or Parsley, in addition to fresh or frozen fruit, ice, yogurt or milk. Other herbal or nutritional supplements can also be added. These beverages are blended into a smooth, thick, milkshake-like consistency. They are extremely easy to make, taste great and provide great nutrition.
