Shopping List


Begin by making the pickled cucumber. Cut the cucumber in half lengthways and scoop out the seeds. Slice crossways into very thin slices

Place the rice vinegar, sugar, salt and ginger into a small bowl and stir to combine

Add the cucumber to the bowl and stir to coat the slices evenly with the mixture. Refrigerate for at least 1 hour

Preheat the oven to 200°C/gas mark 6

Meanwhile, prepare the baked aubergine. Place the miso, mirin and sake in a large bowl and mix together to form a smooth paste. Stir in the ginger and spring onions. Add the aubergine slices to the bowl and toss to coat thoroughly in the sauce

Grease a large roasting tray with the oil and arrange the aubergine slices in a single layer to ensure they cook evenly. Bake for 20 minutes, until soft and golden brown. If the aubergine is drying out, splash with a little water

While the aubergine bakes, prepare the Japanese rice. Place the rice in a sieve and wash under the cold tap until the water runs clear. Rest the sieve on a bowl and leave to drain for at least 15 minutes

Remove the aubergine from the oven and sprinkle with the sesame seeds and chopped coriander. Set aside until ready to serve

Place the rice in a saucepan and add 180ml of cold water. Bring to the boil, cover with a lid and immediately reduce the heat as low as possible for a further 10 minutes. Turn off the heat, do not remove the lid and leave for another 10 minutes

Meanwhile, cook the peas with a pinch of salt in plenty of boiling water for a couple of minutes, then drain and place the peas in bowl of iced water

Place the spring onions, ginger, oil, rice vinegar, mirin, sugar and salt into a small bowl and mix to create a sauce. Fold the peas and sauce into the rice and allow to cool

For the steak teryaki, place a frying pan over a high heat until really hot. Add the oil and flash fry the beef fillet for a couple of minutes. It should still be pink in the middle. Season with salt and pepper and transfer to a plate

Place the mirin, soy sauce, sugar, rice vinegar, cornflour and ginger in a small saucepan. Bring slowly to the boil, stirring continuously, and cook for 2 minutes until the sauce thickens. Leave to cool

Place 2 lettuce ‘cups’ in each bento box and fill with radishes, cucumber and onion. Season with a little more salt and pepper and place the beef slices on top. Spoon over a little of the sauce and sprinkle with the chopped coriander

Divide half of the Japanese rice between the bento boxes, refrigerating any leftovers. Remove the cucumber from the pickling solution and divide between the boxes. Add the baked aubergine and serve
