Preheat your grill to medium-high heat and ensure the grates are clean and lightly oiled.
Mince the garlic clove and finely chop the fresh dill and parsley.
In a small bowl, whisk together the extra virgin olive oil, lemon juice, lemon zest, minced garlic, dill, parsley, sea salt, and black pepper.
Brush half of the lemon-herb mixture over the salmon fillet and toss the asparagus spears with the remaining half until well coated.
Place the salmon on the grill, skin-side down, and cook for about 4 to 5 minutes without moving it to ensure a good sear.
Add the asparagus spears to the grill grates next to the salmon, laying them perpendicular to the grates.
Carefully flip the salmon and grill for an additional 3 to 4 minutes until the fish is opaque and the asparagus is tender with light char marks.
Remove the salmon and asparagus from the grill and serve immediately for a fresh, nutrient-dense dinner.
