Boil a pot of salted water and cook the pasta according to package directions until al dente, reserving two tablespoons of the cooking water before draining.
Dice the chicken breast into bite-sized pieces and season them evenly with half of the sea salt and black pepper.
Heat a large skillet over medium heat and melt half of the grass-fed butter, then sauté the chicken until golden and cooked through.
Remove the chicken from the skillet and add the remaining butter along with the minced garlic, sautéing for one minute until fragrant.
Add the cooked pasta, sautéed chicken, and reserved pasta water to the skillet, tossing to combine.
Sprinkle in the parmesan cheese, dried oregano, and the remaining salt and pepper, stirring until the cheese creates a glossy coating.
Garnish the noodles with finely chopped fresh parsley and serve immediately while hot.
