Mince the garlic and zest the lemon.
In a small bowl, whisk together the olive oil, lemon juice, lemon zest, minced garlic, dried oregano, ground turmeric, sea salt, and black pepper.
Place the salmon fillet in a shallow dish and pour half of the marinade over it, ensuring it is well coated.
Let the salmon marinate for 15 minutes while preheating the grill to medium-high heat.
Toss the asparagus with the remaining marinade.
Place the salmon on the grill, skin-side down, and cook for 4-5 minutes.
Flip the salmon carefully and grill for another 3-4 minutes until the internal temperature reaches 145 degrees Fahrenheit.
Add the asparagus to the grill during the last 4 minutes of cooking, turning occasionally until tender-crisp and lightly charred.
Serve the golden salmon immediately with the grilled asparagus.
