Potato, Sausage and Cheddar Soup

1 pound bulk sausage

5 large potatoes - cooked and diced

6 cups chicken stock or broth

2 cups milk

1 cup shredded cheddar cheese

1 teaspoon dry thyme

1/2 teaspoon ground sage

Break up sausage and brown well in a large and heavy soup pot.

Add potatoes, stock, milk, thyme and sage. Bring to a boil, reduce to a simmer and cook for 30 - 45 minutes; use the longer time for a thicker soup. Mash slightly with a potato masher if you like and add cheddar cheese. Remove from heat, stir well and serve.
