Instructions
In a large bowl, combine the zucchini, red and yellow bell peppers, red onion, and mushrooms.
In a small bowl, whisk together the balsamic vinegar, olive oil, minced garlic, Italian herbs, salt, and pepper. Pour this mixture over the vegetables, tossing well to ensure they are evenly coated. For enhanced flavor, let the vegetables marinate for about 30 minutes
Preheat a cast iron grill pan over medium-high heat.
Once the grill pan is hot, arrange the vegetables in a single layer. Work in batches if needed to avoid overcrowding.
Cook the vegetables for 3 to 4 minutes per side, turning with tongs, until tender and lightly charred.
Transfer the vegetables to a serving platter. Adjust seasoning with additional salt and pepper if needed.
Garnish with fresh herbs, if desired.
Notes
If vegetables begin to stick or look dry, drizzle with a bit of olive oil and balsamic vinegar for moisture and flavor.
Different vegetables cook at different rates. Add longer-cooking vegetables (like onions and peppers) first, followed by quicker-cooking ones (like mushrooms and zucchini) later on.
