Roast veg & goat's cheese pan bagnat

Preheat the oven to 220°C, gas mark 7. Slice the aubergine into long, 1cm-thick strips and cut the red onion into thin wedges. Put on a large baking tray, brush with the oil and season. Roast for 25 minutes, turning halfway, or until tender. Set aside to cool completely.

Cut the top off the loaf with a serrated knife, then use a small, sharp knife to score a 1 cm wide border all the way around the inside edge of the loaf (this makes it easier to scoop out the inside). Use your hands to scoop out the inside of the loaf and the lid. (You can whizz the unused bread into crumbs and store in the freezer for up to 3 months.) Spread the tapenade all over the inside of the loaf, including the lid.

Arrange the roasted aubergine in the loaf as the base layer, overlapping slightly and cutting to fit, if necessary. Top with a layer of peppers, followed by the cheese rounds, the basil and the onion. Replace the lid and press down. Wrap tightly in foil and chill, weighed down with a plate topped with tins or a heavy object, for at least 4 hours or overnight. Unwrap and cut in wedges to serve.
