肉じゃがNikujaga

Nikujaga (肉じゃが) (meaning meat-potato) is a Japanese dish of meat, potatoes and onion stewed in sweetened soy sauce, sometimes with ito konnyaku and vegetables. Generally, potatoes make up the bulk of the dish, with meat mostly serving as a source of flavor. It usually is boiled until most of the liquid has been reduced. Thinly sliced beef is the most common meat used, although minced/ground beef is also popular. Pork is often used instead of beef in eastern Japan.
