Katsudon is a popular Japanese dish that consists of a bowl of rice topped with a breaded and deep-fried pork cutlet, known as tonkatsu. The cutlet is usually cooked with a mixture of eggs and onions, which creates a savory sauce that enhances the flavor of the dish. This comforting meal is often served in a donburi, a traditional Japanese rice bowl. Katsudon is not only enjoyed for its delicious taste but is also considered a symbol of victory, as the word "katsu" means "to win" in Japanese, making it a popular choice for students before exams.
