In a small bowl stir together rosemary, basil, garlic and pepper.
Heat olive oil in a large frypan over medium heat. Dip pork chops in lemon juice and sprinkle both sides with herb mixture. Place pork chops in frypan and sear both sides, about 7 minutes per side. Reduce heat to low. Sprinkle feta on top of chops; cover frypan and cook until cheese begins to melt, about 5 minutes.
