Preheat oven to 180 degrees C (160 fan) / 355 degrees F and prepare a baking tray by covering it with a layer of baking/parchment paper.
Add 20 g Extra Virgin Olive Oil, 40 g Honey, 150 g Whole Oats to a mixing bowl and stir until all of the oats are coated in the liquid
Add in 100 g Mixed Nuts and 50 g Raisins (if using)
Add the mixture to the prepared baking tray in one even layer. Bake for 10-12 minutes mixing around half way through baking, to ensure that the granola cooks evenly.
Cool and enjoy
