Originating from Japanese cuisine, katsu is a lunch or dinner plate with fried chicken, and has been coated in breadcrumbs. Katsu dan is a Japanese dish containing fried pork, eggs, and veggies. Instead of using fried chicken or fried pork, tofu is used in vegan cooking.
Typically katsu is served with a brown sauce made from pureed fruit or ketchup. In addition to sauce, rice and veggies are also commonly served.
Other variations of this dish include curries.
