Prepare the vegetables except for the cabbage: cut into 1 cm slices, season with salt and pepper and lay in one or more lightly oiled ovenproof dishes, sprinkle over a little more oil and cook in the oven at 400°F/200°C/Reg6 for about 15 minutes or until tender but still firm. Take out and keep warm
