Heat charcoal or gas grill on high.
Rub steaks with olive oil, salt and pepper on both sides. Place red peppers in a bowl and coat lightly with olive oil. In another bowl, combine olives, capers, parsley and a teaspoon of fresh ground pepper. Set aside. Oil the grill grate. Place peppers on hot grill. Cover and grill, turning once until dark brown marks begin to appear and the peppers are crisp and tender. About 5 minutes. Transfer peppers to a cutting board. Oil the grill grate again, this time placing the steaks on the grill. Grill steaks about 6 minutes per side for medium steaks. (130 degrees). While steaks cool and rest, combine olives, capers, grilled peppers, parsley and olive oil in a bowl and combine. Serve steaks topped with olive mixture. Enjoy!
