Bring a large pot of salted water to a boil and cook the chickpea pasta according to package directions, reserving 0.25 cup of pasta water before draining.
Season the chicken breast evenly with garlic powder, 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, then set aside to rest and slice.
In the same skillet, reduce heat to medium and sauté the minced garlic for 1 minute until fragrant.
Add the baby spinach to the skillet and cook until just wilted.
Whisk together the Greek yogurt, grated parmesan cheese, and the reserved pasta water in a small bowl to create a smooth sauce.
Return the cooked pasta and sliced chicken to the skillet, pour in the yogurt sauce, and toss everything together until the pasta is coated in a velvety glaze.
Garnish with fresh chopped parsley before serving.
