Prepare an Italian salad dressing. To do this, combine all the ingredients for dressing in a large deep bowl and whisk lightly. Take 1/2 cup of the total mass, and cover the rest and refrigerate, use it at your own discretion (such a dressing can be stored in the refrigerator for up to 5 days). Turn on the grill to preheat to medium heat.
In a small bowl, combine 1/2 cup Italian dressing, parsley, and basil. On 8 metal skewers, string vegetables, mushrooms and shrimps in turn. Place the kebabs on the grill rack and cook, uncovered, for about 3 minutes, turning the kebabs over once. Then grease the kebabs on all sides with dressing and cook, turning, about 3-4 minutes.
Serve vegetable and shrimp kebabs with hot rice (optional).
