Begin by preheating your oven to 425°F for roasting the asparagus.
Rinse and pat dry the chicken breast. Season both sides with salt and pepper.
In a small bowl, mix lemon juice, minced garlic (from 2 cloves), and olive oil.
Heat a non-stick skillet over medium-high heat. Add the chicken breast and sear for about 3-4 minutes on each side until golden brown.
Pour half of the lemon garlic mixture over the chicken while it cooks, allowing the flavors to meld.
While the chicken is searing, place the asparagus on a baking sheet, drizzle with the remaining lemon garlic mixture, and season with salt and pepper.
Roast the asparagus in the preheated oven for 10-12 minutes until tender but still crisp.
Meanwhile, prepare quinoa according to package instructions (or heat pre-cooked quinoa).
Once the chicken reaches an internal temperature of 165°F, remove from the pan. Let it rest for a couple of minutes before slicing.
Plate your dish by arranging sliced chicken alongside roasted asparagus, and serve with the side of quinoa. Enjoy your balanced, flavorful meal!
