Being creative with leftovers leads to lovely new meals.
The Love Food Hate Waste website has a tool that helps you find recipes for your leftovers. Sunday roast leftovers can be used in many dishes - like sandwich fillings, bubble and squeak, curries, risottos, soups and stews.
Fruit that's past its best is great for making into a smoothie or baking. Try making berry compote (to go with ice cream), apple sauce, banana bread or orange cake.
Vegetables can be put into a stew or made into a tasty soup.
