Step 1

Pat the tofu block dry and cut in half lengthways, then into 1cm- thick slices. Set aside on a plate lined with kitchen paper, then put another sheet of paper and a plate on top to weigh it down while you prepare the braise. Mix the soy sauce with the mirin, gochujang, garlic, sesame seeds, most of the spring onions and 200ml water.

Step 2

Heat the oil in a pan over a medium-high heat and fry the tofu for 4-5 mins on each side until golden brown. Pour in the soy sauce mixture and scatter over the green beans. Bring to a simmer, and cook over a medium heat for 10 mins until the braising liquid has thickened and the green beans are tender.

Step 3

Sprinkle over the remaining spring onions and serve with the brown rice.
