Prepare the Glaze: In a small saucepan, combine balsamic vinegar, honey, garlic, Dijon mustard, and Italian herbs. Simmer over medium heat for 8–10 minutes until reduced and slightly thickened. Set aside.
Prepare the Vegetables: Preheat the oven to 400°F (200°C). Toss vegetables with olive oil, salt, pepper, and dried herbs. Spread evenly on a baking sheet.
Roast the Vegetables: Roast vegetables for 15 minutes, stirring once halfway through.
Cook the Salmon: Season salmon fillets with salt and pepper. Push vegetables to one side of the baking sheet and place salmon on the other side. Brush generously with balsamic glaze.
Finish Baking: Return the baking sheet to the oven and bake for another 10–12 minutes, or until salmon flakes easily with a fork.
