The name is just a Samoanized pronunciation of "chop suey," yet the dish is now treated as thoroughly Samoan comfort food rather than a foreign import.
Glass or egg noodles are stir-fried with corned beef or chicken, cabbage, carrot, and soy sauce into a soft, saucy noodle dish, sold at Apia takeaways and served at nearly every Samoan family gathering.
Why it's made this way: Chinese laborers and settlers arrived in Samoa in the early 20th century, and their noodle stir-fries were absorbed into everyday Samoan cooking, especially around Apia, until sapasui became a fixture of the local diet.
