Blend leftovers into smoothies or soups.

Stems, peelings and other culinary off-cuts odds and ends offer plenty of opportunities for imaginative cooks to whisk up a winning smoothie or soup.

• Take the stems from greens like kale and chard, they’re packed with fibre and nutrients, which makes them an excellent addition to your next smoothie. The tops of beets, strawberries and carrots make great add-ins.
• Other items that would otherwise be discarded can also be thrown into a nutritious blend, including fruit and vegetable peels, wilted herbs, overripe bananas and chopped broccoli stalks. Go on, give it whirl.
