Prep time: 20 minutes Cook time: 20 minutes Combine potatoes and stock in a medium sauce-pan. Bring to a boil; reduce heat and simmer, covered, for about 10 minutes or until potatoes are tender. Let cool slightly, then transfer potatoes and stock to a blender or food processor. Blend until fairly smooth with some small chunks of potatoes remaining. Return mixture to saucepan and heat until boiling. Remove from heat and stir in half-and-half, sour cream, cheese, green onions, bacon, garlic, salt, and pepper. Cook over low heat for 5 minutes more. Spoon into bowls and top with garnishes (additional bacon, green onions, cheese) as desired. Makes 4 servings.
