In two batches, blend coconut water and spinach leaves together in a blender until smooth. 2. Add ground flaxseed meal, apples and avocados, blend until smooth. 3. Add mixed berries and blend until smooth. ** This recipe makes a gallon. I usually use a few pitchers to pour batches of the smoothie into soI can make a large batch at one time. I pour the smoothie in pint sized containers and freeze half of them.
