Set oven to 300F and line a baking sheet with parchment paper
In a large bowl, combine oats, nuts, seeds, dried wild blueberries, salt and cinnamon.
In a small saucepan over medium heat, combine brown sugar, oil and water. Stir until the sugar dissolves and the mixture starts to bubble (about 2-3 minutes). Remove from heat.
Pour the syrup over the oat mixture and stir until everything is well coated.
Spread the mixture evenly on the baking sheet. Bake for 40-45 minutes, stirring halfway through for even baking. If you prefer chunkier granola, press the mixture down before baking and avoid stirring.
Let the granola cool completely on the baking sheet – it will crisp up as it cools.
Keep in an airtight container at room temperature for up to 2 weeks.
