Skinny potato soup

My soup is adapted from http://www.theyummylife.com/baked_potato_soup_recipe

• 6 baking potatoes -- cooked & mashed
• 2/3 cup flour (I used wheat)
• 6 cups 1 % skim milk
• 1 cup fat-fat shredded cheddar cheese
• 1/2 teaspoon freshly ground black pepper
• 1 cup fat free greek yogurt

• Directions

Add flour to large pot. Slowly whisk milk into the flour--keep stirring until it's blended. 

Cook over medium heat, stirring frequently, until it starts to thicken (8-10 minutes). 

Add the mashed potatoes, 3/4 cup cheese, salt, and pepper. Stir until the cheese is completely melted.
Stir in the greek yogurt.

Enjoy!!!
