Preheat the oven to 300°F.
In a large mixing bowl, combine the oats, almonds, flax seeds, coconut, and salt. Stir together until evenly blended.
In a measuring cup, whisk together your olive oil and maple syrup. Pour liquids over the dry ingredients, and stir until the mixture is evenly coated throughout. Sprinkle in your cinnamon and cocoa powder and give the mixture a final stir.
Spread your granola evenly on a large baking sheet covered with parchment paper. Bake for about 10 minutes and then give it a good stir with a spatula before cooking another ten minutes, or until it turns a nice golden brown color. When it’s ready, remove tray from the oven and cool completely before transferring to a large glass jar.
