1Wash, dry, and slice the vegetables: zucchini into 1/2 inch thick rounds, bell peppers into strips, and red onion into wedges.
2Whisk balsamic vinegar, olive oil, minced garlic, Italian seasoning, oregano, salt, black pepper, and optional honey/maple syrup and lemon juice in a large bowl.
3Add vegetables to the marinade and toss until coated, allowing them to marinate for 15–30 minutes.
4Preheat the grill to medium-high heat (400–450°F).
5Place zucchini, peppers, and onions on the grill, turning occasionally, for 3–5 minutes per side until tender but firm.
6Add cherry tomatoes to the grill for the final few minutes, cooking for 2–4 minutes until skins blister.
7Transfer vegetables to a serving platter, garnish with fresh herbs, and serve.

Tips
Use a grill basket for smaller items like onions and cherry tomatoes to prevent them from falling through.
Spread vegetables in a single layer on the grill to avoid steaming.
Add fresh herbs after grilling to maintain their freshness.
Crumbled feta, grated parmesan, or balsamic glaze make excellent finishing additions.
If you prefer softer vegetables, grill them for an additional 1–2 minutes.
For a vegan version, omit honey or use maple syrup and avoid dairy toppings.
