Start by preparing the balsamic reduction.
In a saucepan, combine the balsamic vinegar and honey.
Simmer over medium-low heat until it's reduced by half, about 10 minutes.
Once thickened, set aside to cool.
While the reduction is cooling, preheat your grill to medium-high heat.
In a large mixing bowl, toss the sliced vegetables with olive oil.
Season with salt and pepper.
Lay the vegetables evenly on the grill.
Grill each side for about 2-3 minutes or until they have nice char marks and are tender.
Once done, remove the veggies from the grill and set them aside on a platter.
Generously drizzle the balsamic reduction over the grilled vegetables.
Toss gently to ensure each vegetable piece gets its share of the tangy goodness.
