Method
Preheat the oven to 200C/400F/Gas 6.
Heat a frying pan until medium hot, add the butter, onions and sage and fry gently for five minutes until softened.
Place the breadcrumbs in a bowl with the softened onions and mix to combine. Add the egg and season with salt and black pepper.
Mix well then form into golf-ball sized balls and place on a roasting tray. (If making in advance, the stuffing can be frozen at this stage.) Roast in the oven for 20 minutes until crisp.
