Place any extra stuffing on a large sheet of foil. Drizzle with 1 to 2 tbsp (15 to 30 mL) water or chicken broth to moisten. Stir to mix. Cover with another large piece of foil. Fold edges over to seal and pat down to form a long flat packet. Place on a baking sheet. Heat on rack below turkey during last half-hour of roasting. Or place stuffing in a dish. Cover with plastic wrap and microwave on medium-high until hot, stirring occasionally.
