Preheat the oven to 180C/350F. Line a large baking sheet with parchment paper and set aside.
In a large mixing bowl, combine the rolled oats, salt and nuts.
In a small saucepan or microwave-safe bowl, heat the peanut butter with the syrup until it just begins to bubble. Add the liquid mixture to the dry mixture and combine until fully incorporated.
Spread the granola mixture evenly on the lined sheet and bake for 10 minutes or until the edges start to go slightly golden. Remove the granola from the oven and give it a good mix. Place back in the oven for another 12 minutes, or until golden brown.
Let the granola cool completely, before breaking it apart and adding your mix-ins of choice.
