In a large mixing bowl, combine the sliced zucchini, bell pepper, eggplant, red onion, and cherry tomatoes.
In a separate bowl, whisk together the olive oil, lemon zest, lemon juice, minced garlic, oregano, thyme, salt, and pepper until well blended.
Pour the lemon herb marinade over the vegetables and toss to ensure they are evenly coated. Let them marinate for at least 30 minutes for the flavors to meld.
Preheat your grill to medium-high heat. If using a grill basket, place it on the grill to heat up as well.
Once the grill is preheated, you can either place the marinated vegetables directly on the grill grates or in the grill basket.
Grill the vegetables for about 10-15 minutes, turning occasionally, until they are tender and have beautiful grill marks.
Remove from the grill and transfer the vegetables to a serving platter. Sprinkle with fresh parsley for garnish.
Notes
Let the vegetables marinate for at least 30 minutes for the best flavor.
