Cajun-spiced cauliflower pasta bake

Method

1. Heat the oven to 200ºC fan/gas 7. Bring a large pan of salted water to the boil. Cook the cauliflower florets for 3 minutes or until just tender, then transfer with a slotted spoon to a colander and cool under running water. Transfer the florets to a baking dish. Bring the pan back to the boil and cook the pasta for 1 minute less than the pack instructions. Drain, cool under cold water, then add to the dish with the cauliflower.
2. Meanwhile, put the sweetcorn and 150ml of the milk in a food processor/ blender and whizz to combine. Add the cornflour and pulse again until smooth.
3. Heat the oil in a pan over a high heat, then fry the peppers and all but a pinch of the spice mix for 2 minutes on each side to brown lightly. Add to the baking dish and gently mix everything together.
4. Put the pan back on a medium heat, add the sweetcorn mixture and the rest of the milk, then bring to the boil, whisking often, until slightly thickened (about 5 minutes). Add most of the cheese and stir until melted and smooth. Pour the cheese mixture over the pasta bake, then sprinkle with the remaining cheese and spice mixture. Bake for 15-20 minutes until bubbling and golden on top. Sprinkle with the sliced spring onion and serve.
