Preheat the oven to 170 degrees celsius and line a baking tray with baking paper.
In a bowl, mix together the oats, cinnamon, oil, salt and maple syrup together until well combined.
Pour the oat mixture into the prepared tray, then place in the oven and bake for 10 minutes.
After the 10 minutes, add the pecans and hazelnuts to the granola, give it a mix and then return to the oven for another 10 minutes until the nuts are toasted and granola is golden brown.
Leave to cool on the tray, and then transfer to an air tight container to enjoy for a couple months!
