Place pork chops in a large zip lock bag. Add the sauce and sake. Seal and leave to marinade in refrigerator for at least 30 minutes.
Meanwhile, prepare the salad by placing the ingredients into a large bowl and toss gently to mix well. To make the dressing, place all of the ingredients into a small bowl and whisk to combine. Set aside until ready to serve.
Heat a grill plate on medium-low heat. Remove the chops from the bag and discard the excess marinade. Place chops on grill and cook on each side for 6-7 minutes or until cooked through.
To serve, spoon salad into a serving bowl and drizzle with the dressing. Place the chops on a separate platter and sprinkle with fresh greens to garnish.
