1. Preheat oven to 450 degrees F. Lightly coat a baking sheet with cooking spray.
2. When cool to the touch, cut each potato in half lengthwise and scoop out the flesh, leaving about 1/4" of flesh attached to the skin.
3. In a small bowl, whisk together the olive oil, chili powder, and hot sauce. Brush the olive oil mixture on the insides of the potato skins. Cut each half of the potato skin in half again crosswise. Place the potatoes onto the baking sheet.
4. Mix together the turkey bacon, tomato, and onions. Fill each potato skin with this mixture and sprinkle with cheese.
5. Bake until the cheese is melted and the potato skins are heated through (10-15 minutes). Serve immediately.
