In a large bowl, mix flaxseed, banana, acai puree, microalgae powder, and milk.
Add flour through apple cider vinegar. Mix until well combined. Fold in blueberries.
Heat a non-stick waffle iron on medium heat. Spray with avocado or olive oil spray. Gently pour batter into a circular size. Close the waffle iron and continue to cook for an additional 2 minutes.
Repeat with the remaining batter.
Enjoy!
