Preheat your oven to 400°F (200°C).
Trim the woody ends off the asparagus and place them on a baking sheet. Toss with olive oil, half of the sea salt, and half of the black pepper.
Roast the asparagus for 12-15 minutes until tender and slightly charred.
While the asparagus roasts, season the chicken breast with the remaining salt and pepper.
Heat a skillet over medium-high heat and add the ghee. Once hot, sear the chicken for 5-6 minutes per side until golden and cooked through.
In the last 2 minutes of cooking, add the minced garlic, lemon juice, and lemon zest to the pan, spooning the sauce over the chicken repeatedly.
In a small dry pan, lightly toast the pine nuts over medium heat for 2 minutes until fragrant.
Plate the chicken alongside the roasted asparagus, drizzle with the remaining pan sauce, and garnish with toasted pine nuts.
