Preheat the tabletop grill (or skillet) over medium-high heat (level 8-9 for the LeMax for 5 minutes). Lightly grease the surface with a heat resistant oil, and place the fish skin-side down on the grill. Grill for 1 1/2 minutes, and then turn the salmon over and grill for 2 minutes on the other side. Finally turn the fish over once again and grill with the skin side down for another 6-8 minutes (depending on thickness) until medium rare or to desired doneness.
(Alternatively, you can generously coat the flesh side of the salmon fillets with oil before seasoning, rather than greasing the surface).
