Preheat oven to 150C (300F).

Chop all veg into chunks and place in a large oven-proof dish. Drizzle very generously with extra virgin olive oil.

Cover and bake for 2 hours.

Remove the lid, stir well then continue to bake for another 2 – 2 1/2 hours or until all the veg are tender and the sauce has reduced. Taste season.
