Blend together 80g of strawberries (fresh or frozen), 150g-skimmed milk or fortified light, dairy alternative, a heaped teaspoon of oat bran and 1 tablespoon low fat Greek yoghurt. Blitz to your preferred consistency. The more bubbles you can introduce when blending the more filling this smoothie will be. Serve with a 20g handful of chopped nuts on the side.
