Add sesame oil, rice wine vinegar, maple syrup, avocado oil, coconut aminos, ginger, garlic, scallion and jalapeño to a small bowl and stir to combine.
Wash and pat-dry salmon. Add to a zip-top bag set within a bowl. Pour in the marinade, evenly distribute over the fish, squeeze out all of the air in the bag and seal the top. Transfer to refrigerator and let chill one hour.
Meanwhile, soak a cedar plank in water (at least one hour).
Preheat grill to 350F using indirect heat. (Set one side of the grill on high heat and the other side to medium-low)
Lay the marinated salmon skin side down on the cedar plank (make sure none of the fish hangs off the edges). Place the cedar plank onto the medium-low side of the grill, close the lid and cook for approximately 12-15 minutes for medium-rare to medium centre. Try to keep the temperature inside the grill around 350F.
Remove the plank from the grill, garnish the fish with sesame seeds and scallion tops. Serve the Sesame-Ginger Salmon with Quick-Pickles and a fresh salad or side of choice.
