Preheat your oven to 425°F.
Pat the chicken breast dry and season both sides with salt, pepper, and half of the chopped fresh herbs.
In a shallow dish, combine lemon juice, the remaining herbs, and a splash of olive oil. Marinate the chicken for 10 minutes.
Meanwhile, toss trimmed asparagus in a teaspoon of olive oil, salt, and pepper, and spread on a baking tray.
Arrange the marinated chicken on a separate baking sheet lined with parchment paper.
Roast both the chicken and asparagus in the oven. Cook the chicken for about 20-25 minutes until it reaches an internal temperature of 165°F and becomes crispy on the outside. Roast the asparagus for 12-15 minutes until tender.
While the chicken and asparagus are roasting, prepare the quinoa according to package instructions if not already cooked. Fluff with a fork once done.
Plate the chicken alongside a serving of quinoa and roasted asparagus. Drizzle any remaining pan juices or a little extra lemon juice over the top for an added zing.
Serve warm and enjoy your balanced, flavor-packed meal.
