Preheat your oven to 400°F (200°C).
In a small bowl, mix together olive oil, garlic powder, dried basil, salt, pepper, lemon zest, and lemon juice. Place the salmon fillets in a baking dish. Brush each fillet with the olive oil mixture.
In a large bowl, toss the cut vegetables with a bit of olive oil, salt, and pepper. Arrange the vegetables around the salmon in the baking dish.
Bake in the preheated oven for about 20-25 minutes, or until the salmon flakes easily with a fork and the vegetables are tender.
Serve the baked salmon with the roasted mixed vegetables. Optionally, you can drizzle a bit more lemon juice over the top for added zest.
