Preheat a wok over high heat. Combine the soy sauce, sherry, water, and corn syrup in a bowl, mix thoroughly, and set aside. Spray the hot wok twice with the vegetable oil spray. Put the pepper and scallion into the wok, and stir fry for 30 seconds. Add the peas and rice and cook for 2 minutes more, still stirring constantly. Add the soy sauce mixture and toss to coat.
