Pre-heat your oven to 160°C / 320°F (fan-forced).
In a food processor add 360g (4 cups) of the rolled oats and all of the almonds. Pulse until the almonds are chopped up (but not milled to a meal, you want chunks). Thermomix turbo function and check through the lid (about 5 quick pulses).
Place this and the rest of the oats and coconut into a large baking tray. It should form a thin layer (approx. 2cm deep) so use two baking trays if necessary.
Mix the macadamia oil, orange juice and orange zest, rice malt or maple syrup and vanilla together in a jug (or your food processor). Thermomix 30 seconds, speed 4.
Pour over the dry mix and give it a good stir so that all the dry ingredients are coated.
Bake for 15 minutes. Stir well and bake another 15 mins. Repeat if necessary until the mixture is crisp and dry.
Stir again and allow to cool completely.
