Preheat oven to 400 degrees. Wipe shad fillets with damp paper towel. Season both fillets with salt and pepper and wine. Lay one fillet on a large piece of foil and spoon stuffing onto fillet. Top with second shad fillet, dot with butter and wrap up in foil. Place whole package onto a baking sheet and bake about 30 minutes until fish flakes easily. Serve immediately.
