Tjap tjoy

Chop suey is a dish from American Chinese cuisine and other forms of overseas Chinese cuisine, generally consisting of meat (usually chicken, pork, beef, shrimp or fish) and eggs, cooked quickly with vegetables such as bean sprouts, cabbage, and celery, and bound in a starch-thickened sauce. It is typically served with rice, but can become the Chinese-American form of chow mein with the substitution of stir-fried noodles for rice. Chop suey has become a prominent part of American Chinese cuisine, British Chinese cuisine, Filipino cuisine, Canadian Chinese cuisine, German Chinese cuisine, Indian Chinese cuisine, and Polynesian cuisine. In Chinese Indonesian cuisine/Dutch Chinese Indonesian cuisine it is known as cap cai (tjap tjoi) (雜菜, "mixed vegetables") and mainly consists of vegetables. Chop suey is widely believed to have been developed in the U.S. by Chinese Americans, but the anthropologist E. N. Anderson, traces the dish to tsap seui (杂碎, "miscellaneous leftovers"), common in Taishan (Toisan), a county in Guangdong province, the home of many early Chinese immigrants to the United States. Hong Kong doctor Li Shu-fan likewise reported that he knew it in Toisan in the 1890s.
