Chorizo sweet potato soup

2- 3chorizo sausages (the smoked kind)
1 onion
2 bay leafs
4 sweet potatoes and 1 white potatoes peeled and chopped
6 cups of chicken stock
4 leafs of swiss chard, with stem removed and torn up
salt and pepper to taste
2 tsp chili flakes

Fry the sausage until browned, take out and pat extra oil away with a paper towel. In the sausage grease, fry the onions until golden, add potatoes and fry for a few minutes. Then add the stock and the bay leaves, simmering until the potatoes are very soft. Take a potato masher to mash some of the potatoes. Add the sausage and the swiss chard and simmer for 10 more minutes. This is really good, especially the next day. Sorry for the vegetarians, the chorizo gives this soup a really yummy flavour.
