Spoon the skyr into a bowl and stir through the cinnamon. Skyr is naturally rich in protein and keeps you full for longer without spiking your blood sugar.
Chop the walnuts roughly. Scatter them along with the chia seeds over the skyr. The chia seeds will swell slightly and provide extra fibre and omega-3 fatty acids.
Spread the fresh raspberries over the top and finish with a spoonful of almond butter. Mix everything through just before eating so every bite has a combination of creamy, crunchy and fresh.
