Preheat the oven to 160°C.
In a large bowl, mix together the herbs, spices, honey, lemon juice and vinegar.
Add the vegetables and toss around until well coated.
Spray the roasting tin with low-calorie cooking spray, then add the vegetables. Spritz the top with a little more low-calorie cooking spray, then cover with tin foil and cook in the oven for 30 minutes.
Remove the foil, increase the oven temperature to 200°C. Give the vegetables a toss around and return to the oven, uncovered for 15 minutes, or until soft and starting to caramelise.
Serve with your choice of accompaniment.
