It can be grilled, but you will have to grill the fish and make the teriyaki glaze separately.  Brush the flesh side of the salmon with oil and salt then cook over 450-500°F heat directly onto the grates for 6-8 minutes with the lid closed. Flip the salmon and cook for 2-3 more minutes. Add all of the sauce ingredients to a medium saucepan and simmer until thickened then drizzle it over the salmon.
