Preheat your oven to 425°F (220°C) for the asparagus.
In a small bowl, combine the lemon juice, minced garlic, and chopped fresh herbs. Set aside a small amount of this mixture for topping the salmon.
Pat the salmon fillet dry with a paper towel. Brush lightly with a bit of the herb-lemon mixture, and season with salt and pepper if desired.
Place the salmon on a baking sheet lined with parchment paper. Allow the salmon to sit at room temperature while you prepare the asparagus.
Trim the tough ends off the asparagus. Toss the asparagus with olive oil, salt, and pepper on a separate baking tray.
Place both the salmon and asparagus in the preheated oven. Roast the asparagus for about 10-12 minutes until tender, and bake the salmon for 12-15 minutes until it flakes easily with a fork.
While the salmon and asparagus are roasting, prepare cooked quinoa according to package instructions if not pre-cooked.
Once cooked, plate the salmon by drizzling the reserved herb-lemon mixture over the top. Serve alongside the roasted asparagus and a side of quinoa.
Enjoy your nutritious and flavorful meal!
