Place potatoes in large non-stick skillet; add enough cold water to cover potatoes. Bring to a boil over high heat. Reduce heat to medium; simmer, uncovered, 10 minutes or until potatoes are barely tender.
Drain water from skillet; stir in butter, salt, pepper and ham. Cook 3 minutes over medium heat, stirring occasionally. With back of large spoon, make four indentations in potato mixture. Crack an egg into each indentation; cover skillet and cook 2 minutes over medium-low heat.
Sprinkle cheese over potato and egg mixture; cook, uncovered, 3 minutes or until cheese is melted and eggs are set. Top with sour cream, chives or green onion, if desired.
