Stuffing is so simple, and uses so few ingredients, that you can make it as a side dish for chicken at any time, not just Christmas or Sunday lunch. This is a basic sage and breadcrumb stuffing, perfect for poultry.
Alternatively, put all of the stuffing into a lightly greased ovenproof dish. Bake, covered, in a preheated oven at temperatures up to 200C / Gas 6 until heated through, about 40 minutes. Uncover during the last 10 minutes of cooking time to crisp the top.
