Though the chewy texture of Chinese egg noodles is fantastic, you can substitute rice sticks or linguine. Omit or decrease the amount of chile paste if serving to kids.
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.
Curry noodles are a favorite food. I know everything is my favorite food, but Thai street food, especially the kind sold off a boat floating dock side, has to be really good food.
