Heat olive oil in a large skillet. Lightly dust loin chops in flour; when hot, sear chops on both sides for a minute. Lower the heat and cook, uncovered, turning frequently, for 5 to 10 minutes depending on how rare you like them. Remove chops to a plate and pour out most of the fat from the skillet. Add olives, oregano and fresh lemon juice to the skillet, deglaze and reduce. Season with salt and crushed red pepper.
