To make the ratatouille, peel and chop the onions and garlic, halve and deseed the peppers, remove the fibres and cut into 1 cm diamond-shaped pieces; trim the aubergines and the courgettes and dice them into 5mm cubes; scald, skin, quarter and deseed the tomatoes and dice the flesh
Heat the olive oil in a pan and sweat the onion and the garlic until soft; add the peppers and the diced aubergine and cook over a low heat for a further 5 minutes; put in the courgettes and the tomatoes followed by the red wine; season the vegetables with salt and pepper, add the fresh herbs and leave to simmer for a further 5 minutes
Trim the courgettes and cut them diagonally into 15mm thick slices; heat 1 tablespoon of the olive oil and quickly fry the fish fillets in this, on the skin side only
Put the bread, rosemary, thyme, salt and pepper through a food processor
Divide the ratatouille onto 4 individual ovenproof dishes and lay the fish fillets, skin side up, on top; cover the fish with diagonal rows of courgette slices and pile the breadcrumb mixture evenly on top; top with the parmesan cheese and drizzle with the remaining olive oil and bake in a preheated oven at 220C/Gas 8 for 6 minutes
