Clean and cut all the vegetables.
Place the vegetables - if using a BBQ - on 1-2 sheets of foil or foil pans and sprinkle with additional salt and if necessary drizzle with a little extra olive oil. Fold and seal gently or cover pan with foil. Roast for approximately 20-25 minutes or until done, browned and tender.
If roasting in the oven- place vegetables on one or two parchment paper lined cookie sheets and bake in a pre-heated 375 degrees (190 celsius) oven for approximately 30-40 minutes. Turning a couple of times. Bake until tender.
