Soak the cedar plank in water for at least 30 minutes before grilling, but 2-4 hours is ideal.  Heat grill to medium heat. Lay the whole salmon, skin side facing down, on top of the cedar plank. Rub the flesh of the salmon with lemon zest, ginger, garlic, and black pepper. Place on the grill and cover the grill. Grill for 15-20 minutes, or until the salmon is cooked to your liking.Meanwhile, in a small bowl, combine the soy sauce, honey, and chili paste. During the last 5 minutes of cooking, brush the soy sauce mix over the salmon.  Using a large spatula, remove from the grill. Top with salsa and serve.To make the salsa, combine all ingredients in a bowl. Spoon over the salmon.
