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 skillet, let it rest for 3 minutes, then slice into thin strips.
In the same skillet, reduce heat to medium and add the minced garlic clove, sautéing for 30 seconds until fragrant.
Whisk together the Greek yogurt, chicken broth, parmesan cheese, and the remaining salt and pepper in a small bowl.
Add the yogurt mixture to the skillet along with the fresh spinach, stirring until the spinach just begins to wilt.
Toss the cooked pasta and sliced chicken into the skillet, coating everything thoroughly in the creamy sauce before serving.
