Sara'S Low Fat Creamy Cheesy Potatoes - cooking recipe

Ingredients

6 cups potatoes, cubed
2 tablespoons fat-free margarine (I use I Can't Believe It's Not Butter FAT FREE)
1/2 cup onion, chopped
3/4 cup nonfat milk
2 tablespoons flour
1/2 cup plain fat-free yogurt
1 cup low-fat cheddar cheese, divided
1 teaspoon spicy mustard
2 tablespoons parmesan cheese, grated, divided
1/2 teaspoon salt
1/4 teaspoon pepper
1 large green onion, chopped

Preparation

Boil cubed potatoes for 20 to 25 minutes, until just tender. Drain.
Melt fat-free margarine in a saucepan; saute onion until tender.
In a measuring cup, combine milk and flour; add to onions.
Cook and stir a minute or two until thickened.
Turn off heat and stir in yogurt, 1/2 cup cheddar cheese, spicy mustard, 1 tablespoon Parmesan, salt, pepper and green onion.
It's okay that the cheese doesn't melt at this step.
In a mixing bowl, combine hot cooked potatoes and onion/cheese sauce.
Pour into casserole dish that has been sprayed with Pam.
Sprinkle remaining 1/2 cup cheddar and 1 Tablespoon Parmesan cheese over top.
Bake in preheated 350 degree Fahrenheit oven for about 15 minutes until bubbling.
Cool for about 5 minutes to thicken before serving.
