Preheat oven to 400 F. On large baking sheet, arrange potatoes and bake 35 minutes or until tender. Let stand until cool enough to handle.
Cut each potato in half, then cut thin slice from bottom of each potato half. With small melon baller or spoon, scoop pulp from potatoes leaving 1/4-inch shell. Place pulp in medium bowl; set shells aside.
In medium bowl, lightly mash reserved pulp. Stir in remaining ingredients. Spoon or pipe potato filling into potato shells.
Arrange filled shells on baking sheet and broil 3 minutes or until golden and heated through.
