Omurice

Omurice or omu-rice (オムライス, 'Omu-raisu') is an example of yōshoku (Western-influenced style of Japanese cuisine) consisting of an omelet made with fried rice and thin, fried scrambled eggs, usually topped with ketchup. It is a popular dish both commonly cooked at home and often found at western style diners in Japan. Children in particular enjoy omurice. The dish typically consists of chikin raisu(ja) (chicken rice: rice pan-fried with ketchup and chicken) wrapped in a thin sheet of fried scrambled eggs. The ingredients flavoring the rice vary. Often, the rice is fried with various meats (but typically chicken) and/or vegetables, and can be flavored with beef stock, ketchup, demi-glace, white sauce or simply salt and pepper.
