Preheat your oven to 400°F (200°C) and line a small baking sheet with parchment paper.
Trim the woody ends off the asparagus and place the spears on the baking sheet.
Drizzle the asparagus with 0.5 tablespoon of extra virgin olive oil and season with a pinch of the sea salt and black pepper.
Roast the asparagus in the oven for 12-15 minutes until tender and slightly charred at the tips.
While the asparagus roasts, season the chicken breast evenly with the dried oregano, lemon zest, and the remaining sea salt and black pepper.
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 6-7 minutes per side, or until the internal temperature reaches 165°F.
In the final minute of cooking, add the minced garlic and lemon juice to the pan, swirling to combine and spooning the pan sauce over the chicken.
Remove from heat and allow the chicken to rest for 3 minutes before slicing.
Plate the sliced chicken alongside the roasted asparagus and the warm cooked quinoa.
