Roasted vegetable and goat’s cheese lasagne

Method

1. Put the onion, courgette, aubergine, peppers and halved tomatoes in a large roasting tin. Toss with the garlic, chilli, herbs and oil, and season with pepper. Roast for 30-35 minutes until tender. Stir in the canned tomatoes, capers and 2 tbsp water.
2. Meanwhile, melt the butter in a pan over a medium heat. Stir in the flour to make a paste, then cook, stirring, for 1 minute. Off the heat, gradually stir in the milk until you have a smooth sauce. Return to the heat, stirring, for a few minutes to thicken the sauce. Season with nutmeg, salt and pepper. Stir in the vegetarian Parmesan.
3. Divide half of the roasted veg among 4 x 400ml ovenproof dishes. Dot over a third of the goat’s cheese, then top with half the lasagne sheets and a third of the sauce. Repeat, ending with a layer of sauce. Sprinkle with the remaining goat’s cheese, then dot with the quartered cherry tomatoes and thyme leaves. Cool, wrap in cling film, then freeze for up to 3 months.
4. Preheat the oven to 190°C/fan170°C/gas 5. Bake from frozen for 1 hour, or 30 minutes from fresh, until golden and piping hot all the way through.
