Bake potatoes 1 hour at 375° or until tender.  Remove potatoes and reduce oven to 350°,  When potatoes are cool enough to handle, cut them lengthwise into quarters.  *Scoop out pulp, leaving a 1/4 inch shell. 

Combine the butter and taco seasoning.  Brush over both sides of potato skins.  Place skin side down on a greased baking sheet.  Sprinkle with cheese, bacon and onions.

Bake for 5 to 10 minutes or until the cheese is melted.  Serve with salsa and sour cream if desired.
