"Angry." Very spicy tomato sauce with bacon, onion and hot chillis. Traditionally it is served with penne and sprinkled with chopped parsley. Arrabiata in general may mean either hot (spicy) of cooked very hard and fast - bubbling.
"Rabbit in the style of Sardinia." Rabbit minced (US: ground) and browned in oil with the traditional local flavourings of sage and parsley. It is then stewed in white wine and cream and served with pasta and grated Parmesan cheese.
