Stuffing burgers

Heat 1/2 tablespoon olive oil in a frypan over medium heat. Cook the onion for 2-3 minutes until softened, then cool.

Meanwhile, process the bread in a food processor until fi ne crumbs form. Remove the sausages from their casings, and place the meat in a bowl with the breadcrumbs, onion, herbs, egg and lemon zest. Season well with salt and pepper. Using damp hands, form the mixture into 4 large patties, then chill for 10 minutes.

Preheat oven to 180°C. Heat a frypan or barbecue on medium heat. Add remaining 1 tablespoon olive oil and cook burgers, in batches if necessary, for 2-3 minutes each side until brown. Transfer burgers to a baking tray and cook in the oven for a further 6 minutes or until cooked through.

Meanwhile, toast the ciabatta buns. Serve the patties in toasted buns with rocket, sour cream and cranberry sauce.
