Preheat oven to 300℉.
Line baking sheet with parchment paper and set aside.
In a large mixing bowl, combine oats, pecans, coconut, brown sugar, flax seed, chia seeds, cinnamon, and salt. Stir and set aside.
In medium bowl, combine melted coconut oil, maple syrup, egg white, and vanilla. Whisk ingredients until smooth.
Pour wet ingredients over dry ingredients and mix with spatula until just moistened.
Spread granola mixture onto baking sheet and even it out into a thin layer with rubber spatula.
Bake at 300℉ for 45 minutes, making sure not to stir granola while it is baking. This would prevent large clusters from forming. Let granola cool completely and then break clusters apart.
Store in airtight container up to 1 week.
