1. Preheat the oven to 350 deg F. Line a 9" x 9" baking pan with parchment paper and grease the sides with cooking spray. 2. Cook quinoa. It cooks in a 2:1 ratio, so 1/3 cup of quinoa +2/3 cup water. 3. In a large mixing bowl, whisk together the oats, quinoa, sugar, baking powder, salt, cinnamon, and hemp seeds. 4. In a separate bowl, mix the banana, nut butter, eggs, lemon juice and vanilla. 5. Pour this mixture over the dry ingredients, mixing everything together until fully incorporated. The batter should be moist, but not runny. 6. Fold in the blueberries. 7. Transfer the batter into the prepared pan and smooth with a spatula. 8. Bake on the center rack for 25-35 minutes until the bars are golden brown and firm to the touch. 9. Remove and let cool completely in the pan, then remove and slice into squares. Store in an airtight container for 4-5 days.
