Ingredients you’ll need for this recipe

7. Transfer to a serving dish, adjust salt and pepper, and garnish with fresh herbs if you like.

Important Recipe Notes
- Letting the vegetables sit in the balsamic marinade for 30 minutes enhances the flavor, but you can grill them right away if you’re short on time.
- Cut veggies into similar bite-sized pieces for even cooking. Harder vegetables like bell peppers and onions may take slightly longer than zucchini and mushrooms.
- Preheat your grill pan well before adding the vegetables to get nice grill marks. Lightly oil the pan if the vegetables start to stick.
- Taste and add extra salt, pepper, or fresh herbs at the end to suit your preference.
- You can chop and marinate the vegetables ahead of time and store them in the fridge for up to 24 hours. Grill them just before serving.
- This dish pairs well with grilled meats, pasta, or even tossed into a salad for extra flavor.
