How to Make It
Pierce potatoes with a fork; arrange in a circle on paper towels in microwave oven. Microwave at high 16 minutes or until done, rearranging potatoes after 8 minutes. Let stand 5 minutes.
Cut each potato in half lengthwise; scoop out pulp, leaving a 1/4-inch-thick shell. Combine potato pulp, ham, 1/2 cup cheese, 1/3 cup green onions, sour cream, and pepper.
Spoon the potato mixture into shells. Combine 1/2 cup cheese and remaining green onions, and sprinkle over potatoes. Place potatoes on a baking sheet; broil 4 minutes or until golden.
