This is a traditional Turkish dish, mix and match the vegetables however you like, use as a main or as a side dish.
Pre-heat the oven to 200c
In a large bowl toss all the vegetables other than the courgettes with the oil, allspice, coriander and some seasonings
Spread out on a baking tray and place in the oven, turning every 10 mins or so
After 45 mins, gently stir in the courgettes and cook for a further 15 mins
Whilst you are doing this, heat up the passata or sauce with the chickpeas
When the vegetables are all done mix everything together and serve
