Take a leek and win a £250 John Lewis voucher

When looking for healthy, nourishing and seasonal vegetables to add to your shopping trolley this winter, remember the benefits of the British leek – it's a fat-free, nutrient-rich answer to staying healthy and fighting colds

From keeping sore throats at bay to improving the quality of the singing voice, this upmarket onion or poor man's asparagus is a cookery must-have – and it’s one of the few home-grown British vegetables that is actually in season through the colder months.

More refined, subtle and sweet than the average onion and packed with anti-oxidants, the leek has been grown and cooked in Europe for more than 3,000 years. Rich in iron, vitamin B6, vitamin C and folate – it is used to help protect against cancer and in traditional medicines to treat a variety of ailments including the common cold, gout, bad cholesterol and kidney stones.

Competition

To celebrate this most versatile of vegetables, the British Leek Growers' Association is inviting Mumsnetters to submit their favourite leek-based recipe for the chance to win a £250 John Lewis voucher.

Whether you like them roasted, baked, braised or boiled, leeks are easier to digest than onions and have laxative, antiseptic, diuretic and anti-arthritic properties. Just half a cup of leeks counts as one serving, so take a look at the British Leeks website for mouth-watering, seasonal recipes, developed this year, by Telegraph columnist and author Katriona MacGregor.

WIN! One lucky Mumsnetter will win a £250 John Lewis voucher.

Plus, five runners up will receive copies of Katriona MacGregor’s new cookbook, Healthy, Speedy Suppers.

Simply upload your favourite leek-based recipe below to be entered into the prize draw.

Competition closing date: 3 February 2017
