Meat and Potato Casserole

Toss potatoes with butter and salt; arrange in the bottom and up the sides of a greased 12X8X2 inch casserole dish. Bake uncovered at 400 for 25-30 minutes or until potatoes are almost tender. Meanwhile, in a skillet, brown ground beef, drain. Sprinkle beef and vegetable over potatoes. Combine soup, milk, garlic, pepper, onion, and 1/2 cup of cheese; pour over beef mixture. Bake at 400 uncovered for 20 minutes. Remove from oven and sprinkle with remaining cheese. Return to oven and bake an additional 5 min, or until cheese is melted.
