Preheat your oven to 400°F and line a baking sheet with parchment paper.
Trim the woody ends off the asparagus spears and place them on the prepared baking sheet.
Drizzle 0.5 tbsp of olive oil over the asparagus and toss with a pinch of sea salt and black pepper.
In a small mixing bowl, whisk together the remaining 0.5 tbsp olive oil, lemon juice, minced garlic, oregano, and thyme.
Season the chicken breast with the remaining salt and pepper, then brush with half of the lemon-herb mixture.
Heat a non-stick skillet over medium-high heat and sear the chicken for 5 to 6 minutes per side until the internal temperature reaches 165°F.
While the chicken is searing, roast the asparagus in the oven for 10 to 12 minutes until tender and slightly charred.
Serve the chicken and roasted asparagus over the warm quinoa, drizzling the remaining lemon-herb sauce over the plate.
