Heat oven to 350. Layer half the potatoes in a greased baking dish. Sprinkle with half the cheese and half the scallions. Repeat the layers. Pour in broth and season with salt and pepper. Cover with foil and bake 45 minutes. Uncover and bake 35 minutes mor until potatoes are done and dish is golden brown.
This is a delightful little side dish - very simple to make and tasty too.
