Preheat the oven to 180C/350F and grease a large baking sheet.
In a large mixing bowl, add all the veggies and pour the oil over it. Add the spices and, using your hands, mix very well to ensure it's fully coated.
Transfer the vegetables to the baking sheet and roast for 35 minutes, flipping halfway through.
