Cut potatoes in half and scoop out insides, leaving half-inch thick shells. Brush inside of skins with butter.
Place skins on a baking sheet, insides up and bake until crisp.
Remove from oven. Fill halves with remaining ingredients and bake for another five minutes or until cheese melts. Instead of mixing tomatoes with other ingredients, top the skins with tomatoes just before serving.
