For the braised summer vegetables, preheat the oven to 120C/250F/Gas 1.
Heat the rapeseed oil on a medium heat in a large oven-proof saucepan and fry the garlic for 5-7 minutes, or until golden-brown. Add the remaining vegetables, sea salt and freshly ground black pepper and continue to cook for five minutes.
Add the herbs, vinegar and 80g/3oz water. Stir to combine and place in the oven for 75-85 minutes.
To serve, arrange the roasted vegetables on a large platter and garnish with the seeds, parmesan shavings, ham slices and croûtons.
