Potato Bacon Chowder

I had this at a friend's house the other night and HAD to have the recipe! Seriously yummy stuff!

1 onion, diced
1 lb. Bacon
2 cans cream of chicken soup
16 oz. sour cream
1 cup water
2 baked potatoes
¼ c. milk
salt and pepper
garnish with parsley

Cook bacon. Set aside, keeping a little of the bacon grease in the pan to sauté the onion in. After the onion is done, add diced potato and water. Boil for about 5-10 minutes, just make sure the potatoes are soft and cooked all the way through.
Add sour cream, soup, salt, pepper and use milk to reach desired consistency. Add crumbled bacon before serving. Garnish with parsley.
