Celeriac and Apple Soup

I seem to be making soup once a week at the moment and eating it at least once a week too. It's fantastic for when I am going out for dinner as I can save the points for the meal. This soup is especially fantastic as it has no points as its pretty much all veg! It is delicious as well and healthier than the Celeriac and Apple Soup that I made a while ago but just as tasty.

1 onion, chopped
1 tsp curry powder or paste
850ml vegetable stock
250g celeriac, cut into 1 inch cubes
1 cooking apple, peeled, cored and cut into quarters
1 sprig parsley, chopped, to garnish

Spray a saucepan with cooking spray and cook the onion until soft and translucent, about 5 mins. Add the celeriac and the stock, cover and cook for a further 15 minutes.

Add the apple and cook for a further 5 minutes, until the apple has collapsed.

Using a hand blender, blend the soup until smooth. Serve sprinkled with parsley.
