Begin by preheating your grill to a medium-high heat, ensuring it’s hot and ready for cooking.
In a large mixing bowl, combine the sliced zucchinis, red and yellow bell peppers, cherry tomatoes, and red onion. Toss lightly to distribute the vegetables evenly.
In a separate small bowl, whisk together the olive oil, lemon juice, chopped thyme, chopped rosemary, minced garlic, along with a generous sprinkle of salt and pepper. This mixture will serve as your marinade.
Pour the marinade over the assembled vegetables. Use a spatula or your hands to gently toss everything together until each piece of vegetable is coated in the aromatic marinade. Allow the mixture to marinate for approximately 15-20 minutes.
If using skewers, thread the marinated vegetables onto them, alternating the colors for visual appeal. If you opt for wooden skewers, remember to soak them in water for about 30 minutes beforehand to avoid any burning while grilling. Alternatively, you can use a grilling basket for easier handling.
Place the skewers or grilling basket onto the preheated grill. Cook the veggies for about 8-10 minutes, turning them occasionally to ensure even cooking, until the vegetables are tender and exhibit lovely char marks.
Once cooked, carefully remove the grilled vegetables from the grill and let them rest for a few minutes. Serve warm, and drizzle with additional lemon juice if you desire an extra zesty kick.
Notes
For an attractive serving, arrange the grilled vegetables on a large platter and add a sprinkle of extra fresh herbs over the top.
