Stuff the turkey: Place the turkey on a flat surface, season with salt and pepper on the inside and out, and stuff the cavity with the stuffing. Truss the turkey or, alternatively, tie the legs closed with a strong piece of kitchen twine to assure the stuffing doesn't fall out as the turkey roasts. Wrap any remaining stuffing in tinfoil and keep the tinfoil fairly flat, like a large envelope. Roast turkey until 165 degrees F internally. Take the temperature of the stuffing itself to make sure it is cooked through as well.
