Pre-heat your oven to 175ºC/350ºF and line a baking tray with some baking paper.Wash and chop your vegetables into chips, I don’t bother peeling mine, and place on the baking tray. Toss with the macadamia or coconut oil, salt, and pepper and roast for 30 minutes until tender, turning once halfway through.Remove from the oven, let cool for 5 minutes, then toss together with the harissa before serving.
