Cut potatoes in half. Steam until just tender, approximately 15 minutes.
Drain and cool slightly. Scoop out centers of each potato half, leaving skin intact and at least 1/2-inch of potato. Discard potato centers or save for another use. Arrange potatoes on sheet trays, skin side down. Remove small slice from bottom of potato so that it rests flat on sheet tray.
Combine melted butter, Italian Seasoning and garlic seasoning. Brush on potatoes. Broil for 5 minutes or until lightly browned.
Combine sour cream and Gorgonzola cheese. Add walnuts and mix well.
Fill each potato half with cheese mixture. Sprinkle with garlic seasoning. Broil until lightly browned and bubbly, approximately 5 minutes. Remove from heat and sprinkle with chives. Serve immediately.
Potatoes maybe prepared ahead and chilled. To reheat, bake at 375°F for 15 minutes; then broil for 5 minutes or until lightly browned.
