Place the pork chops in a bowl or resealable gallon sized bag.
In a medium sized bowl, whisk together the olive oil, brown sugar, Dijon mustard, soy sauce, lemon zest, parsley, thyme, salt, pepper and garlic.
Pour the marinade over the meat. Marinate for at least 1 hour, or up to 8 hours.
Preheat an outdoor grill or indoor grill pan to medium heat.
Place the pork on the grill. Cook for 6-8 minutes per side or until a thermometer inserted into the thickest part of the chop registers 145 degrees F.
Let the meat rest for 5 minutes, then serve. Garnish with additional chopped parsley if desired.
