Wide rice noodles are available on the ethnic-foods aisle at most major supermarkets and at Asian grocers. If you can't find them, any rice noodle or even spaghetti will work in this dish. You can also use ground sirloin, if you can't find pork.
I've seen sausage-like brochettes in North African restaurants in the past, but I'd never attemped to make them. I like that it's essentially like making a hybrid meatball and sausage, but with no need for stuffing or casing--and more immediate results. The spice combination and the herbs were also intriguing: nutmeg, paprika, cinnamon and cumin.
