Follow these easy steps to prepare your Foil Pack Grilled Vegetables:

1. Preheat the Grill: Start by preheating your grill to medium-high heat (about 400°F or 200°C).
2. Prepare the Vegetables: In a large bowl, combine the bell peppers, zucchini, yellow squash, cherry tomatoes, and corn.
3. Mix the Seasoning: In a separate small bowl, whisk together the olive oil, balsamic vinegar, garlic powder, onion powder, Italian herbs, salt, and pepper.
4. Combine Ingredients: Pour the sauce over the vegetables and toss until evenly coated.
5. Prepare Foil Packs: Cut large sheets of aluminum foil (about 12 inches long). Place an equal portion of the vegetable mixture in the center of each foil piece.
6. Seal the Pack: Fold the sides of the foil over the vegetables to create a sealed packet, making sure there are no openings for steam to escape.
7. Grill the Packets: Place the foil packets on the grill and close the lid. Grill for about 15-20 minutes, depending on the vegetable size. Carefully open a packet to check for doneness.
8. Remove and Serve: Once cooked, carefully remove the foil packets from the grill. Allow to cool slightly before carefully opening them (watch for steam).
9. Season to Taste: Enjoy these grilled veggies as is or add extra seasoning for additional flavor.
