Tender vegetables soak up this tangy marinade and turn delicately smoky and tender on a hot grill. These kebabs make a wonderful side dish with grilled meats or fish.
Whisk oil, vinegar, garlic, Italian seasoning, salt and pepper in a large bowl. Add tomatoes, mushrooms, zucchini and onion slices and toss well to coat. Marinate in the refrigerator for at least 1 hour and up to 4 hours.
Preheat grill to medium.
Remove the onions from the marinade and cut into quarters. Thread the vegetables onto eight 8-inch skewers. Grill, turning once, until tender, 12 to 15 minutes total. Drizzle with the remaining marinade, if desired.
Equipment: Eight 8-inch skewers
