3 Tablespoons butter
1 medium onion, finely chopped
2 Tablespoons cornstarch
1 teaspoon salt
1/4 teaspoon pepper
1 1/2 cups milk
4-6 medium potatoes, peeled and thinly sliced
8 Hot Dogs (make sure to read the label!), quartered and cut into small pieces
1/3 cup cheddar cheese
Melt the butter in a small saucepan. Add onion and saute for 2-3 minutes or until onion is tender. Whisk in cornstarch, salt and pepper until smooth. Gradually add milk and whisk until mixture begins to boil. Cook and stir 1-2 minutes or until slightly thickened (usually it's thick enough by the time it reaches a boil for me, but you'll just have to see what it does for you).
In a large, greased baking dish, layer a third of the potatoes and a third of the hot dogs. Repeat layers twice. Pour sauce over entire dish. Cover with foil. Bake at 350 degrees for 1 hour or until potatoes are fork tender. Sprinkle with cheese and return to the oven for 10-15 minutes or until melted. Serve!
