Pat the cod fillets thoroughly dry with paper towels and season both sides with sea salt and black pepper.
Heat the extra virgin olive oil in a large stainless steel or cast iron skillet over medium-high heat until shimmering.
Place the cod in the skillet and sear for 3 to 4 minutes without moving it to develop a golden crust.
Carefully flip the fish and cook for another 2 to 3 minutes until the internal temperature reaches 145 degrees Fahrenheit and the fish flakes easily.
Remove the cod from the pan and set aside on a plate; lower the heat to medium.
In the same pan, add the ghee and minced garlic, sautéing for 30 seconds until fragrant.
Whisk in the lemon juice, lemon zest, and chopped fresh dill to create a light pan sauce.
While the sauce simmers, steam the asparagus for 3 to 5 minutes until vibrant green and crisp-tender.
Serve the pan-seared cod over the warm cooked quinoa, drizzling the lemon-dill sauce over the fish, with the asparagus on the side.
