Bring a large pot of salted water to a boil and cook the chickpea pasta according to the package instructions until al dente; drain and set aside.
Season the chicken breast evenly on both sides with sea salt, black pepper, and dried oregano.
Heat a non-stick skillet over medium-high heat and sear the chicken breast until golden brown and cooked through to an internal temperature of 165°F, then remove from heat and slice into thin strips.
In the same skillet, reduce the heat to medium and melt the ghee, then add the minced garlic and sauté for 1 minute until fragrant and lightly golden.
Add the fresh baby spinach to the skillet and stir constantly until the leaves are just wilted.
Toss the cooked pasta and sliced chicken back into the skillet, adding the fresh parsley and lemon juice, and stir until everything is coated in the garlic herb sauce.
