2 pounds top sirloin steak -- cut in 2" pieces
MARINADE:
1 cup red wine
1 cup vegetable oil
2 tablespoons vinegar
2 pickled green tomatoes -- quartered
1 large onion -- coarsely chopped
4 large garlic cloves -- minced
3 small dried hot red chiles -- coarsely crumbled
4 whole cloves
1 teaspoon salt
1 teaspoon black pepper
VEGETABLES
4 medium onions -- quartered
4 medium-small firm red tomatoes -- halved
4 pickled green tomatoes -- halved or quartered

In a large non-reactive bowl, combine meat with marinade ingredients; stir to mix well. Cover and refrigerate 12-24 hours, turning meat 2-3 times during that period.

Remove meat from marinade; discard marinade. Thread meat onto skewers, alternating with pieces of onion, fresh tomatoes, and pickled green tomatoes. Grill over hot coals about 10-15 minutes, turning skewers occasionally. Serve immediately.
