I got this recipes from Campbell's Kitchen, about a month ago. I like this recipe, because when you have alot of veggie left overs or just want to have a fresh remake on burgers. So yummy and lots of taste..Try it out you wont regret it.
Place the tomatoes, zucchini, pepper and onion into a large bowl. Add half the dressing and toss to coat.
Lightly oil a grilling platter or vegetable basket. Place the vegetables onto the platter.
Grill the vegetables for 15 minutes or until tender, turning them over once halfway through the grilling time. Remove the vegetables to a large bowl. Add the remaining dressing and toss to coat. Stir in the cheese.
Split the rolls and grill until toasted. Divide the vegetable mixture among the rolls.
