Blender Bender: Parsley, the Unsung Hero
Treated as nothing more than a garnish for color, Parsley gets the short end of the stick. Great for your skin, eyes, even blood, Parsley is an easy low-cal addition to a smoothie or salad, easily picked up at any grocery store. A mild bitter, it will brighten a savory flavor like flaxseed or kale, and can be used in place of lemon or lime (for when you run out taking taquila shots the night before. Hey, it's all about balance, right?!).
Pro Tip: Cut up bananas and throw them in Tupperware so you can enjoy a smooth, filling smoothie anytime. Do NOT freeze with the skin on or you'll have to wait approximately 18 years for it to thaw enough to get in there.
