Tomato, Leek & Sweet Potato Soup

Tonight I had a hankering without a recipe. And you know that those must be honoured so...

1 tbsp butter
1 small leek, green only
crushed garlic
1/2 large sweet potato
4 small tomatoes, seeded and diced
some chicken or veg broth
1 small can tomato paste
2 1/2 tbsp fat free cream cheese

Cook the leeks and garlic in the butter until it smells fabulous. Add tomatoes & sweet potatoes. I added some rosemary and basil at this point too. Add stock. Let boil until potatoes are tender. Let cool slightly and then blend up in batches. Return to pot and add cream cheese and tomato paste.
Serve with dollop of sour cream, salt and pepper and freshly grated parmesan cheese.

I love what can be whipped up with what's in my fridge!
