30 minutes prior to grilling, prepare your cedar plank by soaking it in water. (A large roasting pan filled with a couple inches of water works well. Submerge the plank in water by holding it down with a heavy item like a bottle of wine or jar of sauce.) Let the plank soak fully for at least 2 hours. DON'T SKIP THIS STEP!

Using an outdoor gas or charcoal grill, light it for medium high heat. Don't use a cedar plank indoors.

When plank has been soaked, place your fully thawed salmon fillets on the plank. Sprinkle fillets with salt and pepper to your taste. Next sprinkle on the minced garlic and dill. Lastly, slice the lemon in half. Squeeze one half of the juice of the lemon onto the fillets. Slice the other half of the lemon in slices, then the slices in halves. Place the halves on top of the salmon.

Place the prepared salmon onto the hot grill. Check the salmon on occasion to ensure the plank isn't flaming up. Use a spray bottle filled with water to shoot out any flare-ups. Grill for 12-15 minutes, or when salmon flakes. For a thicker salmon, increase grill time appropriately. Safely remove the hot plank from the grill with grilling tongs. Transporting on a baking sheet works well, as the plank will be very hot.

Serve right away with additional lemon wedges if desired.
