Preheat oven to 180 °C and line a baking tray with baking paper.
Place oats, nuts and seeds in a large mixing bowl. Place oil and honey or sugar in a separate bowl and melt in the microwave or a small saucepan over low heat for a few minutes. Stir in the vanilla.
Mix oil mixture well into oats mixture.
Spread oats in a single layer on the baking paper. Roast for 10 minutes. Stir through and roast for another 8-10 minutes or until golden brown and crispy.
Remove from the oven and allow to cool completely. Store in an airtight container for up to 4 weeks.
Serve ½ cup (125 ml) muesli per person with ¼ cup (60 ml) plain low-fat yoghurt and ½ cup (125 ml) of any fresh fruit. Add a pinch of cinnamon for more flavour.
Use seasonal fruit like peaches, mangoes, grapes or berries in summer and pawpaw, banana, grapefruit, kiwi or naartjies in winter. Remember that ½ cup (125 ml) fruit is 1 portion.
