How to Make It
Preheat the broiler, and position a rack about 6 inches from the heat.
In a small bowl, combine the hoisin sauce, ginger, soy sauce and vegetable oil.
Rinse the tilapia fillets under cold running water, then arrange them in a small ovenproof dish. Pour in the sauce over the fish, and turn it over in the sauce so that both sides are coated.
Broil the fish for 10 to 12 minutes, until the tilapia flakes easily and is cooked through. Serve topped with sauce from the pan.
