Throw some chicken, veg, avocado and cherry tomatoes into a wrap with some lemon juice and greek yoghurt for a nutritious, lean protein-packed, low-carb lunch. Feel free to swap out the wrap for two slices of wholemeal sourdough bread if you’d prefer – or for a vegan alternative, smash half a cup of cooked chickpeas in with the avocado instead of the grilled chicken.
