Soup is a great meal to batch cook in order to set yourself up for the week with tasty and nutritious lunches that mean you don’t have to revert to supermarket sandwiches.

And this one is particularly good as it’s packed with superfoods including sweet potato and kale, plus lentils.


Otherwise known as leaf cabbage, kale is grown for its edible leaves. Curly kale is the most common variety, however you can get kale with smooth leaves.

You can buy it all year round, but it is in season from mid-September to late February.

Eat it within two or three days of buying as it gets bitter the longer it is left.

Sweet potatoes

Sweet potatoes originate from Central and Southern America, and are a different shape and texture to potatoes most commonly found in the UK and Europe. Unlike white potatoes, they also count as one of your five-a-day.

They have orange flesh and a softer texture when compared to other varieties of potato.

Roast sweet potatoes to increase the sweetness. You can also make them into a tasty alternative to fries, chips or wedges.


Lentils are an edible pulse. They are very versatile in cooking and provide many dishes with a boost in protein as well as fibre content, and nutrients that are essential for prime body function.

Add lentils to soups or stews to thicken dishes, plus add some extra protein and fibre.
