Butternut soup

Nothing's more delicious than a bowl of soup in winter, so I decided to make some butternut soup. I'm actually a bit embarrassed to put this recipe up because it's so incredibly easy but here it is anyway. Enjoy!

1kg butternut, peeled and chopped
2 large onions, chopped
1/2 teaspoon mild curry powder (add more or less depending on how hot you like your soup)
olive oil to fry the onions
750ml vegetable stock
1/2 teaspoon cinnamon 
Fresh cream and feta cheese to serve

Fry the onions until soft. Add the curry powder and fry for 3 minutes. Add the butternut and vegetable stock. Allow to simmer until soft (this depends on the size of your butternut pieces- the smaller they are, the quicker they will soften). Add the cinnamon and blend until smooth.
