How to Make It
In a large bowl, combine the wine with the olive oil, vinegar, garlic, coriander, peppercorns and oregano. Put the steaks and pork chops in 2 large, deep dishes and add half of the marinade to each. Cover both dishes and let the meats marinate in the refrigerator for 4 to 8 hours, turning occasionally.
Light a grill. When it is moderately hot, drain the marinade and add the steaks and chops in batches. Grill the chops until just cooked through, 7 to 8 minutes per side. Grill the steaks until medium rare, 2 1/2 minutes per side for skirt or 12 minutes per side for sirloin.
