Boil the chickpea pasta in salted water according to package directions, reserving 2 tablespoons of the cooking water before draining.
Season the chicken breast with sea salt and black pepper on both sides.
Heat the olive oil in a large skillet over medium heat and cook the chicken for 5-6 minutes per side until golden and cooked through.
Remove the chicken from the skillet, let it rest for 2 minutes, then slice into thin strips.
In the same skillet, add the minced garlic and sauté for 30 seconds until fragrant and lightly toasted.
Add the fresh spinach to the skillet and cook until just wilted.
Lower the heat to low and stir in the Greek yogurt, grated parmesan, and chicken broth until a smooth sauce forms.
Add the cooked pasta and sliced chicken back into the skillet, tossing well to coat in the velvety sauce.
Stir in the reserved pasta water if needed to reach your desired creamy consistency.
