how long to grill salmon?
1 If the fillets still have skin, remove it after grilling.  To grill salmon on a charcoal grill, place the fish on the grill rack directly over medium coals. Grill, uncovered, for 4 to 6 minutes per 1/2-inch thickness or until fish begins to flake when tested with a fork. Turn the fish once halfway through grilling. If you like, brush the salmon with olive oil or melted butter after turning to add flavor and keep it moist.
