Cook the cocktail sausage (chipolatas) under a hot grill for 5-6 minutes, turning frequently. Meanwhile, make the sage and onion stuffing mix according to the packet (usually just adding hot water). Cut the bacon rashers (slices) in half. Wrap 10 of these round the sausages and secure each with a short wooden cocktail stick pushed right through the roll. (If you soak your cocktail sticks in water for an hour before cooking, you'll find they won't burn). Roll the sage and onion stuffing into sausage-size and sausage-shape balls and wrap them in the remaining 10 lengths of bacon, again securing with a cocktail stick. Cook under a preheated grill (broiler) for about 3-4 minutes, turning frequently.
