1. Combine potatoes, egg, salt and pepper in medium bowl. Use hands to mix well. Coat mini muffin pans with non-stick cooking spray. Spoon 2 heaping tablespoons of potato mixture into each muffin cup. Use fingers or back of spoon to press mixture firmly on bottom and sides of muffin cups.
2. Bake in preheated 450°F oven about 20 minutes or until potatoes are golden brown. Sprinkle cheese into each potato nest; return to oven and bake 2 minutes or until cheese melts. Top with sour cream and bacon and, if desired, additional cheese.
