Create a quick and delicious stir-fry by using your food processor to make a flavorful soy sauce-based sauce. Combine soy sauce, ginger, garlic, and a bit of cornstarch in the food processor and blend until smooth. Heat some oil in a wok or skillet, add your choice of fish fillets, and stir-fry until cooked. Pour the sauce over the fish and vegetables, and toss until everything is well coated. Serve over steamed rice for a satisfying meal.
