15 Days of Superfruit Smoothies: Separate superfruits into 15 Tupperware containers and store in the freezer. Superfruits contain lots of antioxidants. Freeze alongside 15 bags of kale, spinach, or a combination of both. Use one Tupperware of superfruits as one bag of kale per smoothie. Add walnuts, ground chia seeds, and ground flax seeds for your Omega-3s. Add a liquid of your choice such as coconut milk, coconut water, almond milk, or juice. This makes smoothie a snap every morning!
