Preheat your oven to 400°F (200°C) and line a rimmed baking sheet with parchment paper for easy cleanup.
Rinse the quinoa in a fine-mesh strainer and place it in a small saucepan with 0.5 cup of water; bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes.
Pat the chicken breast dry with a paper towel and rub with 0.5 tsp of the olive oil, sea salt, black pepper, and dried thyme.
In a small bowl, whisk together the remaining 1 tsp of olive oil, melted ghee, lemon juice, lemon zest, and minced garlic.
Place the chicken breast on the prepared baking sheet and roast in the oven for 10 minutes.
While the chicken is roasting, trim the woody ends off the asparagus spears.
Remove the baking sheet from the oven, place the asparagus next to the chicken, and drizzle the lemon-garlic-ghee mixture over both the chicken and the vegetables.
Return the sheet to the oven and roast for an additional 10 to 12 minutes, or until the chicken reaches an internal temperature of 165°F and the asparagus is tender.
Fluff the cooked quinoa with a fork and plate it alongside the roasted chicken and asparagus, garnishing the entire dish with fresh chopped parsley.
