Laos khao soi is one of the best hidden gems in the world of noodle soups. It has a garlicky tomato meat sauce that gives this dish its wonderful flavour and colour. It is also known as “spaghetti pho” because it literally looks like bolognese sauce on top of pho rice noodles. But unlike pho, khao soi is ridiculously simple and cheap to make which is perfect for families and those who want something different but are on a budget.
