Use at least 1 frozen fruit for a refreshingly cold smoothie
Use coconut water instead of regular water for an electrolyte boost
Note that this recipe uses less water than normal smoothies because the orange acts like fruit AND liquid. If your orange is extra watery, don't be afraid to lessen the amount of water to start.
Feel free to swap spinach with any leafy green you have on hand (kale works great in this recipe too!)
