Preheat oven to 180°C/356°F (conventional). Line a large baking tray with baking paper.
Add rolled oats, pecans, sunflower seeds and pepitas to a large mixing bowl and stir to combine.
Add the macadamia oil, honey, tahini, ground ginger, ground cinnamon, ground nutmeg, ground cloves and sea salt flakes to a medium mixing bowl. Whisk until well combined.
Pour the honey mixture into the oats mixture and stir to through to evenly coat.
Tip the granola mixture out onto the baking tray. Spread out across the base of the tray and press down with the back of a spatula. Place the baking tray onto the middle shelf of the oven and bake for 20 minutes.
Once baked, remove from oven and allow to cool completely before breaking up into clusters. Transfer the cooled granola clusters to a glass jar or airtight container and store at room temperature.
