Soak skewers in water for at least 1 hour. In a bowl, toss together pork, lemon juice, red wine vinegar, oregano, thyme, garlic, olive oil, salt and pepper. Cover and refrigerate for 3 hours or overnight. On the 8-inch skewers place 5 pieces of meat. Lay on a hot grill and grill slowly (no flame) continuing to brush on marinade, until meat is done. Serve immediately in a pita, topped with Shredded Salad.
Toss all the ingredients in a large bowl, taste and adjust seasonings.
