Preheat oven to 325°F.
In a medium bowl, combine the rolled oats, sunflower seeds, pumpkin seeds, and sesame seeds.
Drizzle the olive oil and maple syrup over the dry ingredients and stir to coat evenly.
Add the garlic powder, onion powder, cayenne pepper, and salt. Stir to combine.
Spread the granola mixture in a single layer on a baking sheet.
Bake for 15-20 minutes, stirring halfway, until lightly golden brown.
Allow to cool completely before serving or storing in an airtight container.
