Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Toss the asparagus spears with the extra virgin olive oil, half of the sea salt, and half of the black pepper.
Roast the asparagus for 10 to 12 minutes until tender and slightly crisp at the tips.
Pat the cod fillets completely dry with paper towels to ensure a proper sear, then season both sides with garlic powder and the remaining salt and pepper.
Heat the ghee in a large non-stick skillet over medium-high heat until shimmering.
Place the cod in the skillet and sear for 3 to 4 minutes without moving it, until a golden-brown crust forms.
Carefully flip the fish and reduce the heat to medium. Add the lemon juice and fresh dill to the pan.
Tilt the pan slightly and use a spoon to continuously baste the cod with the lemon-dill ghee for another 2 to 3 minutes until the fish is opaque and flakes easily.
Warm the pre-cooked quinoa and plate it alongside the roasted asparagus.
Place the cod fillet on the plate and drizzle any remaining pan sauce over the top before serving.
