Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Snap off the woody ends of the asparagus and toss the spears with 0.5 tablespoon of olive oil, sea salt, and black pepper.
Spread the asparagus in a single layer on the baking sheet and roast for 12-15 minutes until tender and slightly charred.
While the asparagus roasts, season the chicken breast evenly on both sides with dried oregano and dried thyme.
Heat the remaining 0.5 tablespoon of olive oil in a medium skillet over medium-high heat.
Place the chicken in the skillet and sear for 5-7 minutes per side, or until the internal temperature reaches 165°F.
In the final 2 minutes of cooking the chicken, add the minced garlic to the pan and sauté until fragrant, being careful not to burn it.
Remove the skillet from the heat and immediately stir in the lemon juice and lemon zest, scraping up any browned bits from the pan to glaze the chicken.
Serve the pan-seared chicken alongside the roasted asparagus over a bed of warm, fluffy cooked quinoa.
