First off, arrange all the vegetables in an oven safe dish, season and drizzle with olive oil.
Roast for 40 minutes until soft at 180 degrees Celsius.
Meanwhile add the coriander, almonds, parmesan and garlic in a pestle and mortar or food processor if you want, pound or blend these ingredients adding a oil as you go a long.
More oil will result in a less dense pesto.
Serve grilled vegetables with pesto and fresh coriander.
