Sweet Potato Soup

1/2 stick of butter (I used smart balance)
2 cups finely chopped onion
6 cups chicken broth
5 cups peeled and cubed fresh yams or sweet potatoes
5 cups peeled and cubed russet potaoes
1 cup peeled and shredded russet potatoes (about 1 med)
1/2 cup heavy cream (I am going to try using fat free half and half)
2 t. ground cumin
1 t. dried parsley
1/4 t. salt
ground black pepper to taste

Melt the butter in a large stockpot over med-high heat. Stir in onions and saute until soft. Add broth and sweet potatoes, bringing to boil, then lowering heat and simmering for 10 min. Add the potatoes, return to simmering and cook until the potatoes are soft. Stir in the cream, cumin, parsley, salt and pepper. Cook over low heat, stirring often until heated through.
