Preheat the oven to 325° and line a large baking tray with parchment paper.
In a large bowl mix the oats, cashews, almonds, flax seeds, sesame seeds, chia seeds, cinnamon, and salt until combined.
Add the coconut oil, maple syrup, and vanilla extract. Mix until dried ingredients are well coated.
Pour mixture onto the parchment-lined baking tray. Smooth over to ensure an even layer.
Bake for 20 minutes, remove from oven and give it a good stir.
Bake for another 15-20 minutes, or until the mixture is golden brown.
Remove from oven and let cool for 20 minutes.
Once cooled, break apart with your hands or spoon. Store in an air-tight container or enjoy immediately.
