Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Toss the sliced cremini mushrooms with half of the ghee, minced garlic, sea salt, and black pepper on the prepared baking sheet.
Roast the mushrooms for 15-18 minutes until they are golden brown and tender, stirring halfway through the cooking time.
While the mushrooms roast, season the chicken breast with a small pinch of sea salt and black pepper on both sides.
Heat the remaining ghee in a skillet over medium-high heat and sear the chicken breast for 6-7 minutes per side until the internal temperature reaches 165°F.
Fluff the cooked quinoa with a fork and place it in a serving bowl as your nutritious base.
Slice the seared chicken breast into strips and arrange it neatly over the bed of quinoa.
Top the dish with the golden roasted mushrooms, fresh thyme leaves, and a bright drizzle of lemon juice before serving.
