You could change vegetables to suit your taste, but remember to slightly pre-cook any tougher [root vegetables] in the microwave first, as they may not cook as well as the softer vegetables.
We all know we are supposed to eat our veggies, roasting them makes it that much easier!! Pick any kind the family will eat and maybe one they don't and roast till slightly crunchy, Texture is Huge! No one like mush veggies. I did forget to use the balsamic but still delish! ! I'm from the U S A and having a ball playing in your sandbox Thanks so much! This is always welcome on my bbq! - 03 May 2013
