In a saucepan, whisk together 2 cups water, 1/2 cup soy sauce, 1/4 cup honey2 teaspoons toasted sesame oil,1/2 cup brown sugar, 2 teaspoons granulated garlic, and 2 teaspoon ground ginger. Mix 1/4 cup cornstarch with 1/2 cup water, then stir it into the sauce. Bring the mixture to a low boil, whisking continually until sauce is thickened. Remove from heat and let cool slightly.
Once the marinade has cooled, divide it in half. Pour one portion over the pork chops in a zip-top bag, ensuring they are well coated. Seal the bag and refrigerate for at least 1 hour and up to 4 hours. Reserve the remaining marinade for serving.
Prepare a grill fire 250° - 300° using hickory or oak for smoke flavor. Remove pork chops from the marinade, discarding remaining marinade. Grill for about 8-10 minutes per side or until the internal temperature reaches 145°F.
Remove from grill and rest for 5 minutes before serving.
Warm the reserved marinade and serve it over the grilled pork chops for an extra punch of teriyaki flavor. Garnish with sliced green onions if desired.
