Rinse the quinoa under cold water and place in a small saucepan with the water.
Bring the water to a boil, then reduce heat to low, cover, and simmer for 15 minutes until the liquid is fully absorbed.
While the quinoa cooks, season the salmon fillet with half of the sea salt and black pepper.
Heat the extra virgin olive oil in a non-stick skillet over medium-high heat.
Place the salmon in the pan and sear for 4 to 5 minutes per side until the exterior is golden and the fish is cooked through.
Steam the asparagus spears in a separate pot for 3 to 5 minutes until they are bright green and crisp-tender.
Fluff the cooked quinoa with a fork and stir in the lemon juice, lemon zest, fresh parsley, and the remaining salt and pepper.
Plate the lemon-herb quinoa and top with the pan-seared salmon, serving the steamed asparagus on the side.
