Preheat your gas grill to medium-high heat and spray with nonstick cooking spray. Slice a 3-inch pocket into each of the pork chops.
In a small bowl, mix the cream cheese, Parmesan cheese, spinach, garlic, thyme and oregano. Stuff each of the pork chops evenly with the stuffing and seal the edges with a toothpick.
Grill the pork chops in direct heat for 2-3 minutes until each side gets grill marks. Then remove the chops to indirect heat and close the grill. Grill until they reach an internal temperature of 145°F.
Garnish with freshly chopped parsley, if desired.
