In 12-inch nonstick skillet, heat oil over medium-high heat. Cook potatoes in oil 10 to 12 minutes, stirring frequently, until golden brown. Add pork; cook about 5 minutes, stirring frequently.
Reduce heat to medium. Add remaining ingredients except parsley. Cook 4 to 6 minutes longer, stirring occasionally, until pork is no longer pink in center. Top with parsley.
