Mix oatmeal, nuts, seeds, and coconut chips together in a large bowl.
Add cinnamon powder and salt to the bowl.
In a small bowl, combine olive oil and maple syrup, mixing well.
Pour the liquid mixture over the oatmeal mixture and toss until well coated.
Spread the mixture thinly on a parchment-lined baking sheet.
Bake in a preheated oven at 180°C for 20-25 minutes, stirring once halfway through.
Let it cool, then mix in dried fruits as desired.
