If using, prepare the cedar plank by fully submerging it in water for at least 2 hours.
Place salmon filets into a shallow pan.
Mix the sweet chili sauce, tempura sauce, cilantro, garlic, and ginger together into a bowl. Pour the mixture over the salmon and marinate in the refrigerator for one hour.
Remove cedar plank from water and arrange lemon slices to cover the top of the plank. Once complete place salmon on top and pour the extra marinate. Preheat the gas grill to medium high heat. Place planks onto the grill for 12 to 15 minutes until salmon is cooked.
If not using cedar planks, grill the salmon on each side for 3 to 4 minutes or roast in the oven at 425 degrees for 12 to 15 minutes.
Serve on the plank with your favorite side dishes for a summer BBQ.
