In a small bowl combine oil, Parmesan cheese, salt, garlic powder, paprika and pepper. Mix well.
Brush this mixture over the tops and bottoms of each potato skin.
Bake at 450 for 8 minutes. Add cheese and bacon and bake for 2 more minutes.
Sprinkle on green onions or chives. Serve warm with ranch or sour cream
