Preparation:
Preheat your oven to 400°F (200°C).
Line a baking sheet with parchment paper or lightly grease it.
Prepare the Vegetables:
In a large bowl, toss the chopped mixed vegetables with 2 tablespoons of olive oil, minced garlic, dried thyme, salt, and pepper.
Spread the seasoned vegetables in an even layer on the prepared baking sheet.
Bake the Vegetables:
Place the baking sheet with the vegetables in the preheated oven and roast for about 15-20 minutes, or until they start to become tender and slightly caramelized. Stir the vegetables halfway through cooking.
Prepare the Salmon:
While the vegetables are roasting, brush the salmon fillets with the remaining 1 tablespoon of olive oil and season with salt and pepper.
Bake the Salmon:
After the vegetables have roasted for about 15-20 minutes, push them to the sides of the baking sheet to make space for the salmon fillets.
Place the seasoned salmon fillets in the center of the baking sheet.
Return the baking sheet to the oven and continue baking for an additional 10-15 minutes, or until the salmon is cooked through and flakes easily with a fork.
Serve:
Once the salmon and vegetables are done, remove them from the oven.
Divide the roasted vegetables onto plates and top each portion with a baked salmon fillet.
Serve with lemon wedges on the side for squeezing over the salmon and vegetables.
