In a small bowl, stir together soy sauce, brown sugar, water, and vegetable oil until sugar is dissolved.
Place fish in a large resealable plastic bag with the soy sauce mixture, seal, and turn to coat. (I just put it all in the bowl with the soy sauce mixture and turned it several times.)

Cook salmon for 6-8 min. per side or until the fish flakes easily with fork
