Put the pork chops into a large zip-top bag, and fill with marinade of olive oil, garlic, rosemary, basil, sea salt and pepper
Marinate in the refrigerator for at least 30 minutes
In a mixing bowl, whisk the lemon juice, olive oil, balsamic vinegar, garlic, sea salt and pepper together, and use for basting
Remove pork chops from bag, discard sauce, and set gas grill to medium heat
Grill chops on heavy-duty aluminum foil for about 4 minutes per side,(depending upon thickness) and baste with the sauce
Remove chops to a platter and cover with foil
Place remaining sauce in a small saucepan, and cook on medium high heat for about 1 minute or until sauce begins to thicken
Pour sauce over pork chops, and serve immediately
