In a small bowl, stir together the flaxseed meal and water. Let sit for 2-3 minutes, or until thick and gelatinous.
In a large bowl, combine the oats, nuts, seeds, coconut, salt, cinnamon, brown sugar and popped quinoa.
Mix together the maple syrup, honey, mixed flaxseed meal and oil. Stir it into the the dry ingredients until well coated.
Spread the granola mixture evenly on baking sheet. Use the back of a wooden spoon to press it down, trying to keep the layer as thin as possible.
Bake for 20 minutes. Rotate and bake for another 15 minutes. Remove and let cool completely to room temperature. Scrape the high protein granola off the baking sheet with a spoon and transfer to an airtight container.
