Mutton sausages are the best. Knock pork sausages into a cocked hat
Then any joint that suits slow roast. And chops, ahh.... mutton chops
Just roast with some moisture (wine or water, according to taste!), onions and tomatoes or apricots.. and you'll never want lamb again...
Oh, and lasagne made with mutton mince? Spoils you for all other lasagnes....
