In a large shallow pan, submerge 2 grilling planks in water and allow to soak at least 30 minutes.
Prepare a medium-high heat grill, about 400 degrees F.
Brush the fillets on both sides with olive oil, and sprinkle evenly with Seattle Salmon Rub.
Remove the planks from the soaking pan and place a piece of salmon on each one.
Place the planks on the grill and close the lid. Cook for 10-12 minutes. The fish is done when it flakes easily and you can see white streams of fat coming out from between the flakes on the side of the fillet. Serve immediately.
