Rinse the quinoa under cold water and place in a small saucepan with 0.5 cup of water.
Bring quinoa to a boil, then reduce heat to low, cover, and simmer for 15 minutes until the water is absorbed.
Pat the tilapia fillets dry with paper towels and season both sides with sea salt and black pepper.
Heat the olive oil in a large non-stick skillet over medium-high heat.
Add the tilapia to the skillet and sear for 3 to 4 minutes per side until the fish is golden and opaque throughout.
Remove the fish from the pan and set aside on a plate.
In the same skillet, add the minced garlic and asparagus spears, sautéing for 4 to 5 minutes until tender-crisp.
Stir in the ghee, lemon juice, and chopped parsley, scraping up any browned bits from the bottom of the pan.
Return the tilapia to the pan briefly to coat with the sauce, then serve alongside the fluffy quinoa and asparagus.
