Bring a pot of salted water to a boil and cook the chickpea pasta according to package directions until al dente.
While pasta cooks, season the chicken breast with half of the sea salt and black pepper.
Heat olive oil in a large skillet over medium-high heat and sear the chicken for 5-6 minutes per side until golden and cooked through.
Remove chicken from the pan, let it rest for 2 minutes, then slice into bite-sized strips.
In the same skillet, reduce heat to medium and melt the grass-fed butter, then sauté the minced garlic for 1 minute until fragrant.
Add the cooked pasta, sliced chicken, fresh parsley, lemon juice, and remaining salt and pepper to the skillet.
Toss everything together until the pasta is coated in the silky butter sauce, then serve topped with grated parmesan.
