Sprinkle pork chops with pepper flakes, salt and pepper. In a large skillet, heat oil over medium heat. Add pork; cook for 5-7 minutes on each side or until meat reaches desired doneness (for medium-rare, a thermometer should read 145°; medium, 160°). Remove and keep warm., In the same skillet, whisk the vinegar, honey, green onions, garlic, rosemary, salt and pepper; bring to a boil. Reduce heat; simmer, uncovered, for 6-8 minutes or until slightly thickened, stirring occasionally. Remove from the heat; whisk in butter until melted. Serve with pork chops.
