With this fully tomato filled bowl, you cannot see the beef and onion from here. There is cooked sliced beef and onion underneath. ( As well as rice. )
Steamed white rice, 100 grams sliced beef, 2 chopped tomatoes, 1/2 sliced onion. Soy sauce, Mirin ( sweet rice wine ), Sake ( or white wine ), some oil ( I used grape seed oil )
1. Heat the pan. Put 1 table spoon of oil into the pan. Start cooking onion and then beef.
2. Season onion and beef with soy sauce ( 1 table spoon ). mirin ( 1 table spoon ) and sake ( 2 tea spoon ) . You can change the volume of these seasoning depending on your taste.
3. Keep cooking onion and beef for 3 min. to 5 min.
4. Put onion and beef on the rice. Add chopped tomato on onion and beef. Done !
I read several doctor's comment on how to control the weight. It seems it is better to prepare several dishes since it takes more time to finish and it will avoid too much eating. ( The signal of " I ' m full " will be sent to your brain if it takes more time. ) However, for lunch or quick meal, I cannot take much time, so when it is only one dish, I try to chew well before swallowing them.
