Preheat the oven to 350°F with a rack in the center position.
Line a rimmed baking sheet with parchment paper. Set aside.
In a large bowl, combine the oats, pecans, chia seeds, pumpkin seeds, almonds, sesame seeds, coconut flakes, salt, and cinnamon. Stir in the maple syrup, coconut oil and vanilla.
In a small bowl, beat the egg white until peaks have formed. Gently fold the egg whites into the oat mixture.
Pour the granola onto the prepared baking sheet. Using the bottom of a measuring cup, gently press the granola into an even layer.
Bake until the oats and nuts are golden brown, about 20 minutes.
Let the granola cool for 10 minutes before breaking it apart. Store in an airtight container for up to 1 month.
