Hot Dog Casserole

3 tablespoons butter or margarine
2 tablespoons all-purpose flour
1 to 1-1/2 teaspoons salt
1/4 to 1/2 teaspoon pepper
1-1/2 cups milk
5 medium red potatoes, thinly sliced
1 package (1 pound) hot dogs, halved lengthwise and cut into 1/2-inch slices
1 medium onion, chopped
1/3 cup shredded cheddar cheese

In a saucepan, melt butter. Stir in flour, salt and pepper until smooth. Gradually add milk. Bring to a boil; cook and stir for 2 minutes or until thickened and bubbly.

In a greased 2-1/2-qt. baking dish, layer a third of the potatoes, half of the hot dogs and half of the onions. Repeat layers. Top with remaining potatoes.

Pour white sauce over all. Cover and bake at 350° for 1 hour. Uncover; sprinkle with cheese. Bake 10-15 minutes longer or until potatoes are tender. Makes 8 servings.
