1. Preheat oven to 450°.
2. Pierce potatoes with a fork. Bake potatoes at 450° for 50 minutes or until done; cool slightly. Cut each potato in half lengthwise; scoop out pulp, leaving a 1/4-inch-thick shell. Combine potato pulp, milk, 3/4 cup cheese and remaining ingredients in a large bowl.
3. Spoon potato mixture evenly into 10 shells; discarding remaining 2 shells. Sprinkle remaining 1/2 cup cheese evenly over potatoes. Bake at 450° for 15 minutes or until thoroughly heated.
