Scrub 4 oval-shaped baking potatoes (about 2 pounds total); pierce potatoes with a fork. Arrange about 1 inch apart on a large microwave-safe plate. Microwave on 100 percent power (high) for 12 to 18 minutes or until tender, turning the potatoes after 6 minutes. Remove from oven. Cover the cooked potatoes with foil; let stand for 6 minutes while preparing topping.
