Preheat an oven to 220°C/gas mark 7

Bring the vegetable stock to the boil in a saucepan, then add the millet and miso paste. Turn the heat down and simmer for 15 minutes

Meanwhile, drain the tinned sweetcorn and place half of it in a blender. Blitz to a smooth purée and set aside

Toss the cavolo nero leaves in oil, salt and pepper, then cook in the oven for 10–15 minutes until crisp

Meanwhile, place a frying pan over a high heat. Once smoking hot, add the rest of the drained sweetcorn and cook for a few minutes until blackened and charred. Remove from the pan and keep warm

Clean the frying pan and place back over a high heat. Slice the mushrooms lengthways and lightly score a crisscross pattern into the cut side. Drizzle a little oil in the pan and place the mushrooms cut-side down. Fry for 3–5 minutes depending on the size of the mushrooms, then flip over to reveal a nice golden colour

Season the mushrooms with a pinch of salt, then remove from the pan. Leave to rest for a couple of minutes while you plate the rest of the dish

Fold the sweetcorn puree into the millet, which should be soft in texture but a little loose like a risotto. Taste and season with salt, pepper and a splash of sherry vinegar

Plate up the millet topped with the mushrooms, cavolo nero and charred corn
