Meat Loaf and Potato Casserole

Preheat oven to 375 degrees. Coat an 8-inch square baking dish with nonstick cooking spray. In a large bowl, combine ground beef, cracker crumbs, onion, egg, chili powder, and salt; mix well. Press into the baking dish and bake 25 to 30 minutes, or until juices run clear. Drain off excess liquid. In a medium bowl, combine potatoes, corn, and green onions. Spread over the meat loaf and sprinkle with cheese. Bake 8 to 10 more minutes, or until cheese melts and top begins to brown.
