Preheat your oven to 425°F.
Place the chicken breast on a clean cutting board. Pat it dry with a paper towel.
Zest half a lemon over the chicken and drizzle with olive oil. Squeeze in the juice from the lemon half.
Season the chicken with mixed herbs, minced garlic, a pinch of salt, and black pepper. Press the seasonings into the meat.
Heat a non-stick skillet over medium-high heat and sear the chicken for 2-3 minutes on each side until it develops a golden, crispy exterior.
While the chicken sears, trim the woody ends off the asparagus and place them on a baking sheet. Drizzle with a small amount of olive oil, and season with a pinch of salt and pepper.
Roast the asparagus in the preheated oven for about 10 minutes, or until tender and slightly charred.
Transfer the seared chicken to the oven (if needed, use the same baking sheet after removing asparagus) for an additional 6-8 minutes, or until the chicken is cooked through.
Plate the crispy lemon-herb chicken alongside the roasted asparagus and serve immediately.
