Method:

Preheat oven to 200°C/180°C fan-forced. Heat the olive oil in a frying pan over medium heat. Cook onion, stirring for five minutes or until translucent. Add the breadcrumbs, orange zest and pistachios and cook for a few minutes more then remove from heat. 

Cut away the string from your lamb and place on a board. Press stuffing into the centre of the meat, pushing in as much as you can. Tie tightly with string, taking extra care to close up the filling. Place in a large roasting pan and surround with the kipfler potatoes. Rub meat with oil and drizzle a little extra olive oil over the potatoes. Season everything well with sea salt and freshly ground black pepper and roast for 1 hour and 15 minutes (this should result in lovely pink meat). Remove lamb from the tray and set on a chopping board. Cover with foil then return the tray with the potatoes to the oven.

Let the lamb rest for 20 minutes while the potatoes get a final blast. Slice and serve with steamed beans, the potatoes and Beerenberg Mint Jelly. Yummo!
