Wrap each potato in microwavable plastic wrap; place on microwave-safe plate. Microwave on HIGH 3 minutes; turn over and continue microwaving 3 minutes more or until potatoes are tender.
Meanwhile, stir together all remaining ingredients in small bowl. Carefully remove plastic wrap from hot potatoes. Cut each in half lengthwise; fluff with fork. Place 1 tablespoon flavored spread on top of each half potato.
