Rinse the quinoa thoroughly in a fine-mesh strainer and place in a small saucepan with 0.5 cup of water.
Bring the quinoa to a boil, then reduce heat to low, cover, and simmer for 15 minutes until water is absorbed.
Season the chicken breast evenly with half of the sea salt and half of the black pepper.
Heat the extra virgin olive oil in a large stainless steel or cast-iron skillet over medium-high heat.
Place the chicken in the skillet and sear for 6 to 7 minutes per side until the internal temperature reaches 165 degrees Fahrenheit.
Remove the chicken from the skillet and set aside on a plate to rest, keeping the pan on the heat.
Add the minced garlic and asparagus spears to the skillet, sautéing for 3 to 4 minutes until vibrant and crisp-tender.
Pour in the chicken broth and lemon juice to deglaze the pan, scraping up any browned bits from the bottom.
Stir in the fresh parsley and the remaining salt and pepper, then serve the chicken over the quinoa with the asparagus and a drizzle of the pan sauce.
