Completely immerse the cedar plank in water, placing a weight on top to keep it totally covered. Soak for at least 1 hour.

Preheat the grill to medium-high heat.

In a small bowl, combine the dressing, sun-dried tomatoes, and basil; set aside.

Remove the plank from the water. Place the salmon on the plank; place on the grill and close the lid. Grill for 10 minutes then brush the salmon with the dressing mixture. Close the lid and grill for 10 more minutes, or until the salmon flakes easily with a fork.
