Scrub and pierce potatoes. Bake at 400° for 40-60 minutes or microwave, uncovered, on high for 12-14 minutes or until tender. Meanwhile, in a skillet, cook the sausage over medium heat until no longer pink; drain.
When potatoes are cool enough to handle, cut in half lengthwise; scoop out pulp, leaving a 1/4-in. shell. In a large bowl, mash the pulp with butter. Stir in the sausage, cheese, ham, bacon, sour cream, salad dressing, salt and pepper.
Spoon into potato shells. Place on two ungreased baking sheets. Bake at 400° for 30 minutes or until golden brown.Yield: 16 servings
