Preheat the oven to 425°F (220°C).
Place chopped vegetables on a baking sheet. Drizzle with 1 tbsp olive oil, season with salt, pepper, and herbes de Provence. Toss to coat.
Roast the vegetables for 20–25 minutes, flipping halfway through, until tender and golden.
Meanwhile, heat 1 tbsp olive oil in a nonstick skillet over medium-high heat.
Season salmon with salt and pepper.
Place salmon skin-side down in the skillet. Sear for 3–4 minutes until the skin is crispy.
Flip and cook the other side for another 2–3 minutes until cooked through.
Serve the salmon alongside the roasted vegetables.
