1. Place all ingredients except the white nectarines into a medium-sized bowl and stir to combine.
2. Transfer the bircher mix into an airtight container and place in the fridge for 3-24 hours (the longer the better) – the oats should be soft and all liquid should be absorbed.
3. Once ready serve the bircher muesli with white nectarine slices, coconut flakes and a dollop of yoghurt.
