Bring a pot of salted water to a boil and cook the chickpea pasta according to package directions, reserving 2 tablespoons of pasta water before draining.
Season the chicken breast with garlic powder, sea salt, and black pepper.
Heat olive oil in a skillet over medium-high heat and sear the chicken until golden and cooked through, then set aside to rest and slice.
In the same skillet, reduce heat to medium and sauté the minced garlic and fresh spinach until the spinach is just wilted.
Whisk together the Greek yogurt, grated parmesan, and reserved pasta water in a small bowl until smooth.
Combine the cooked pasta, sliced chicken, and spinach in the skillet, then pour the yogurt sauce over the top and toss gently until creamy.
Garnish with fresh parsley and serve immediately.
