Wash potatoes and bake in 350 degree oven for about an hour. Do not prick the potatoes. Remove from oven and cool.
Slice potatoes in half lengthwise and scoop out the soft insides with a spoon. Get as much out as possible without puncturing the skin. Spray both sides of the skin with non-fat cooking spray and season with salt and pepper.
Place back in a 350 degree oven for about 3-5 minutes, until crisp.
Mix sour cream, garlic and chives. Season lightly with salt and pepper.
Fill each potato skin with tomatoes, scallions, bacon, bell pepper, and cheese. Place back in oven until cheese melts, about 2-3 minutes.
