Preheat the oven to 400°F (200°C).
In a saucepan, bring the vegetable broth to a boil. Add the quinoa, reduce the heat to low, cover, and simmer for 15-20 minutes or until the quinoa is cooked and the broth is absorbed.
Meanwhile, season the salmon fillets with salt, pepper, and lemon juice. Place them on a baking sheet lined with parchment paper.
Toss the mixed roasted vegetables with olive oil, salt, and pepper. Spread them out on a separate baking sheet.
Place both the salmon and vegetables in the preheated oven. Bake for 12-15 minutes or until the salmon is cooked through and the vegetables are tender.
Remove from the oven and serve the baked salmon on a bed of cooked quinoa, alongside the roasted vegetables.
Drizzle the salmon and vegetables with additional lemon juice if desired.
Serve immediately and enjoy!
