Sara'S Low Fat Creamy Cheesy Potatoes

• 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

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