Preheat your oven to 425°F.
In a small bowl, combine the juice of 1/2 lemon, chopped fresh herbs, minced garlic, salt, and pepper.
Pat the chicken breast dry and rub half of the herb mixture over both sides to infuse flavor. Allow it to marinate for 10-15 minutes at room temperature.
Place the chicken on a baking sheet lined with parchment paper.
Toss the asparagus with olive oil, salt, and pepper, then spread them alongside the chicken on the baking sheet.
Bake in the preheated oven for about 20-25 minutes, or until the chicken reaches an internal temperature of 165°F and the asparagus are tender with a slight char.
While the chicken and asparagus are baking, heat the cooked quinoa on the stovetop or in the microwave until warm.
Slice the baked chicken and plate with the roasted asparagus and warmed quinoa. Drizzle any remaining herb marinade over the top for an extra burst of flavor.
Serve immediately and enjoy your zesty, crisp, and comforting meal.
