In a large, heavy-bottomed skillet, place onions and peppers in 2 tablespoons oil. Saute over medium heat until soft, about 8 minutes. Set aside. Add 2 tablespoons more oil to skillet. Add beef. Saute meat, until it is browned. Add celery salt, oregano, basil, salt, black pepper, garlic, cayenne pepper, and reserved onions and peppers. Mix well.
Add tomato sauce and Worcestershire sauce. Stir to blend. Cook 10 minutes over medium heat, so flavors mingle. Stir occasionally. Add olives, capers, and raisins. Cook over low heat, covered, for 40 minutes. Add reserved olive juice, if needed for consistency.
