Let's make it
In large bowl, whisk oil and seasoning; add remaining ingredients and toss.
Prepare grill for direct grilling over medium-high heat. Place 4 (12 x 14-inch) sheets aluminum foil on work surface; divide vegetable mixture onto center of foil sheets. For each packet, bring top and bottom sides of foil together over vegetables; crimp together and fold down over vegetables. Double fold both ends of packets toward vegetables.
Place packets on hot grill rack; cover and cook 12 minutes, turning once. Makes about 8 cups.
