Boil the chickpea pasta in salted water according to package directions until al dente, then drain and set aside.
Steam the broccoli florets in a steamer basket over boiling water for 3 to 4 minutes until tender-crisp and vibrant green.
Season the chicken breast with sea salt and black pepper.
Heat olive oil in a large skillet over medium-high heat and sear the chicken for 5 to 6 minutes per side until cooked through.
Remove the chicken from the skillet and let it rest for 2 minutes before slicing into thin strips.
Reduce the skillet heat to low and add the minced garlic, sautéing for 30 seconds until fragrant.
Whisk in the Greek yogurt, chicken broth, and parmesan cheese until a smooth, creamy sauce forms.
Add the cooked pasta, steamed broccoli, and sliced chicken back into the skillet, tossing gently to coat everything in the sauce.
Garnish with freshly chopped parsley and serve immediately.
