For many of us Christmas lunch is one of the most nutritious meals of the year and a festive highlight. But it’s also the time when we spend the most and waste the most.

This Christmas, Australians will discard more than one quarter of the food they buy, much of which ends up in polluting landfill. Not only is food wasted, but also the land, water, energy and animals used to produce it and the important nutrients it contains.

Meat and vegetables are full of protein, fibre and vitamins needed for good health. A lunch including two roast potatoes, a spoonful of peas and two pieces of broccoli provides over half the recommended amount of vegetables an adult should eat in one day.

The dilemma is working out the right amount to buy and cook. If you find yourself with leftovers, you can transform them into simple recipes. Here are two to use your valuable leftover turkey, ham, veggies and salad.
