Cut the ends off the oranges and remove the skin and pith with a sharp knife, remove the segments catching the juices in a bowl. Add just the orange segments to the remaining fruit.
Tumble together the fruit, walnuts, muesli and yogurt and divide between 2 bowls to serve.
Cooks tip
Try other flavours of yogurt or simply go plain. For vegans, try plant-based yogurts or coconut yogurt alternative.
