Preheat your grill or a heavy grill pan over medium-high heat.
Mince the garlic clove and finely chop the fresh dill and parsley.
In a small mixing bowl, whisk together the extra virgin olive oil, fresh lemon juice, lemon zest, minced garlic, dill, parsley, sea salt, and black pepper.
Brush half of the prepared lemon-herb mixture over both sides of the salmon fillet and the asparagus spears.
Place the salmon on the grill skin-side down and cook for 4 to 5 minutes without moving it to ensure a good sear.
Add the asparagus spears to the grill alongside the salmon and cook for 3 to 4 minutes, turning occasionally until tender-crisp with light char marks.
Carefully flip the salmon fillet and cook for an additional 2 to 3 minutes until the flesh is opaque and flakes easily with a fork.
Arrange the warm cooked quinoa on a plate, top with the grilled salmon and asparagus, and drizzle the remaining herb mixture over the top before serving.
