Pat fish dry, season with pepper and place in baking dish. Heat oil in
medium skillet or wok until hot. Add vegetables and stir-fry over high
heat until tender-crisp, about 3 minutes. Combine soy sauce and corn
starch, add and stir-fry about 1 minute longer. Spoon vegetable mixture
over center third of fish, fold over ends of fish to enclose
vegetables. Cover with foil. Bake at 350 degree F about 10 minutes or
until fish flakes easily. Serve with rice if desired.
