Crock Pot Potato Soup

8 cups diced potatoes
1/2 cup chopped onion
3 cans (14 1/2 oz. each) chicken broth
1 can (10 3/4 oz.) condensed cream of chicken soup, undiluted
1/4 tsp. pepper
8 oz. cream cheese, cubed
1/2 lb. sliced bacon, cooked and crumbled
snipped chives, optional

In a crock pot, combine the first 5 ingredients. Cover and cook on low for 8-10 hours, or until potatoes are tender (if using chopped frozen potatoes, don't cook as long). Add cream cheese; stir until blended. Garnish with bacon and chives if desired.
