Rub pepper over both sides of steaks. Put in refrigerator for 15 minutes. In ungreased skillet, brown steaks on both sides over medium-high heat. Reduce heat to medium. Add butter and garlic. Cook for 4-6 minutes, turn steaks once. Add Worcestershire sauce; cook 4-6 minutes longer, turning once, or until meat reaches desired level of cooking (for medium-rare, a thermometer should read 135°; medium, 140°; medium-well, 145°). Remove steaks and keep warm.
