2 tablespoons light margarine 
1 tablespoon all-purpose flour 
1 1/2 cups skim milk or 1 can (15 ounces) fat-free, low-sodium chicken broth 
1 cup leftover mashed potatoes 
1/4 teaspoon black pepper 
1/2 teaspoon onion powder 
One of the following: 1 ounce leftover diced lean ham, 1 ounce chopped lean sandwich meat, or 1 regular-size, low-fat hot dog, diced 
1 ounce low-fat cheese (Cheddar, Swiss, or American), shredded 
 
In a small saucepan, melt margarine over medium heat. Add flour and whisk to make a paste. Add skim milk and stir constantly over medium heat and bring to a slow boil to thicken slightly. Add mashed potato, black pepper, onion powder, and chopped meat. Bring to a boil, then cover and reduce heat to simmer. Simmer 2 minutes. Spoon soup into bowls, then top each with a quarter of the shredded cheese.
