Preheat the oven to 300 degrees F and line a baking pan with parchment paper. Mix the oats, sliced almonds, hemp seeds, cinnamon, and salt together in a bowl. Mix the maple syrup, vanilla extract and coconut oil together in a separate bowl. Pour the liquid into the bowl of dry ingredients and mix together until everything is evenly coated. Spread out evenly on the baking pan and bake for 25-30 minutes, until lightly toasted. Let cool then mix in the dried blueberries.
