Scalloped Potatoes

Ingredients:
3 Tbsp. margarine
3 cups milk
2 Tbsp. flour
1 tsp. salt
1/4 tsp. pepper
7 medium potatoes, cooked and sliced
2 Tbsp. onion, diced

Directions:
Preheat the oven to 350 degrees. In a medium saucepan, combine the margarine, milk, flour, salt, and pepper. Stir over medium heat until melted and smooth. Meanwhile prepare your cooked potatoes by slicing them into thin slices. Add the onions to the potatoes and mix together. Layer half of the potatoes in a greased 9x13 pan and top with half of the sauce. Repeat again with the other half of potatoes and sauce. Cover the pan with tinfoil and bake at 350 degrees for 1 hour. After the hour is up, remove the tinfoil and continue baking until the top is browned.
