Donburi to a Japanese means a bowl of rice served on a bowl also called donburi. Rice topped with a dish say Teriyaki Beef is called Teriyaki Beef Donburi. On Western menus, they have it as Beef Teriyaki Donburi but a Japanese lady I replaced at work said the proper way to say it is Teriyaki Beef Donburi.For the sauce� cup teriyaki sauce4 tbsp of mirinFor the beef2 tbsp of olive oil1 lb of beef1/8 or a little bit more of teriyaki soyFor the vegetables2 medium carrots, julienne cut¼ cabbage, shaved200 grams of bean sprouts1 small onion, sliced thinlySimmer the teriyaki sauce and the mirin on slow fire for about 15 minutes. Marinate beef for about 15 minutes.Once the two procedures above have been done, prepare the pan for cooking the beef.In a very hot pan, put in the marinated beef, discarding the marinating sauce. Add oil. Do not cover the pan and it should be hot enough to allow whatever liquid is left in the beef to evaporate. Stir occasionally. Cook for about 5 minutes and set aside.In the same pan, put all the vegetables in and cover the pan. Cook for about 4 minutes stirring occasionally. When vegetables are cooked, turn off the stove and add the sauce and the green onions. Serve on top of rice.I am sure you can do it too. Try it.
