Mary Berry served up tasty posh roasted vegetables on Mary Berry’s Foolproof Cooking.

Mary says: “This is a different take on a classic ratatouille with the vegetables arranged prettily in a dish. Serve in slices.”

The ingredients are: 2 medium aubergines, cut into 1cm slices, 2 red peppers, deseeded and cut into 1cm slices, 500g courgettes, cut into 1cm slices, 6 tbsp olive oil, 2 red onions, finely chopped, 2 garlic cloves, crushed, 500g tomato passata, 1 tsp caster sugar, 1 small bunch fresh basil, chopped, 50g gruyère cheese, grated, 2–3 large tomatoes, each cut into 8 wedges, 2 tsp chopped fresh thyme leaves and salt and freshly ground black pepper.
