Variation: The veggies may also be chopped fine, marinated together and tossed like a salad. This can be spooned onto the rolls and cover with cheese and top half. Proceed as above. Note: These rolls can be foiled cooked or directly cooked on a bar-b-que mesh, but tie a string so the veggies cheese do not fall out. Another option is to bar-b-que the veggies first and then put them in the rolls.
