This great technique of steam-poaching, using the juices from vegetables and a little butter, is easy to adapt to whatâs around or in season, and is useful for a fridge-foraging lunch or supper as well as a healthy big breakfast. This is a high-protein breakfast that will really fill you up, but as it is quite high in calories it should be paired with lower calorie lunch and/or dinner on a diet day. Each serving provides 457 kcal, 23g protein, 42g carbohydrates (of which 5g sugars), 20g fat (of which 8g saturates), 9g fibre and 1.6g salt.
