Bring a large pot of salted water to a boil and cook the whole wheat penne according to package directions until al dente.
While the pasta cooks, season the chicken breast with half of the sea salt and black pepper.
Heat a large skillet over medium-high heat and sear the chicken for 5-6 minutes per side until golden and cooked through, then set aside to rest and slice into strips.
In the same skillet, lower the heat to medium and melt the ghee, then add the minced garlic and sauté until fragrant but not browned.
Stir in the baby spinach and cook until just wilted, then add the cooked pasta, sliced chicken, fresh parsley, and fresh basil to the pan.
Toss everything together with the remaining salt, pepper, lemon juice, and parmesan cheese until the pasta is evenly coated and glistening.
