Heat your oven to about 180C.
Prepare the vegetables to roast. I have not put the amounts for this as you can choose how much of each you want to cook.
Toss the vegetables in some rapeseed oil, balsamic and sea salt.
Lay out on a baking tray and cook in a hot oven for about 30 minutes or until tender.
Boil the cous cous for about 10 minutes or as per instructions in the packet in some stock for flavour.
When ready, combine the cous cous with the roasted vegetables.
Adjust seasoning, drizzle more Extra Virgin olive oil and serve immediately.
