Heat the oil in a large skillet over medium heat for 5 minutes. Add the
onion, green pepper, and garlic, and saute for a few minutes, until the onion
becomes translucent and the pepper tender.
Add the ground beef, pork, ham, and sausage, and saute, stirring constantly,
until all the ingredients mix and the meats brown. Stir in the capers, season with
salt and pepper, and add the olives, stirring constantly. Add the tomato sauce
and wine, lower heat, and simmer, covered, for about 25 minutes.
When the mixture is thoroughly cooked, remove from heat and serve
