In a large bowl, combine oatmeal, all nuts, and craisins.
In a smaller, separate bowl, whisk together maple syrup, olive oil, brown sugar, salt, and cinnamon. Pour over oatmeal mixture and stir until well combined.
Coat a large rimmed baking sheet with a little olive oil and spread mixture out into a single layer.
Bake for 45 minutes. Remove from oven at 15 minute intervals and stir. Mixture will be golden brown and well toasted when done.
Cool completely. Store in jars or other airtight container.
