Butadon is one of our favourite Japanese dishes to make and eat. And extremely easy and fast to do.
In a pan of oil at medium heat, sweat half a sliced onions until they are slightly charred, soft and translucent. Once they are soft, add your pork shabu into the mix. Use a pair of tongs to separate the pieces as they tend to stick together.
Once the meat is seared for about a minute or less, add 1 tbsp light soya (or 2 tbsp udon/soba sauce), 1 tbsp mirin, half tsp sugar and 2 tbsp water. Simmer for about a minute.
