Oyakodon

Oyakodon (親子丼), literally "parent-and-child donburi", is a donburi, or Japanese rice bowl dish, in which chicken, egg, sliced scallion (or sometimes regular onions), and other ingredients are all simmered together in a sauce and then served on top of a large bowl of rice. The name of the dish is a poetic reflection of the fact that both chicken and egg are used in the dish.
Variations
Several other Japanese dishes pun on the parent-and-child theme of oyakodon. Tanindon (他人丼), literally "stranger bowl", is otherwise identical but replaces the chicken with beef. A dish of salmon and roe served raw over rice is known as sake oyakodon (鮭親子丼).
