Step 1Toss together the cilantro, parsley and oregano in a large glass bowl. Stir in the onion, garlic, vinegar, water, olive oil and salt to taste.
Step 2Add the pork chops and toss to coat. Cover and marinate them in the refrigerator about 1 hour.
Step 3Heat the grill or a grill pan.
Step 4Remove the pork chops from the marinade and lightly spray them with cooking spray. Grill the chops over hot coals or on a stove-top grill pan until the chops are cooked to medium and slightly pink in the center (about 160 degrees on a meat thermometer), 3 to 4 minutes per side. Serve with slices of fresh lime.
