Preheat oven to 350 degrees then line a large baking sheet with a silpat or parchment paper. Combine oats, nuts, salt, and cinnamon in a large bowl then stir to combine and set aside.
In a separate bowl, mash bananas until completely smooth and liquidy then stir in coconut oil, maple syrup, and vanilla. Pour into oat mixture then mix with a spatula until coated. Spread out on prepared baking sheet then bake for 15-20 minutes or until golden brown, stirring twice. Cool granola completely on baking sheet – it will crisp as it cools – then stir in dried blueberries. Store in an airtight container at room temperature for 3-4 days.
Notes
Keep in an airtight container so the texture doesn't change!
