I sliced the walnuts and almonds, and cut in half the hazelnuts. The idea is that they have a nice size so that you can get a piece of everything in a spoonful. Be careful with your fingers when cutting them!
Mix everything in a bowl and put on an oven tray or mould lined with baking paper. Push down the granola so that it sticks together and the honey bunches form.
Take to a preheated oven at 180C for 10 minutes at a time, mixing around in between and pressing down again before it goes back in.
Take out once nice and golden and let cool without bringing it apart until completely at room temperature.
