First, add chicken breasts to a medium pot and season with kosher salt & black pepper. Cover with at least 1" of water and bring to a boil. Once boiling, cover with a lid, reduce heat to low and let simmer for about 15 minutes, or until internal temperature reaches 165F. Timing will vary depending on how large/thick your chicken breasts are.

In another large bowl, whisk together the greek yogurt, sun-dried tomatoes & their oil, dijon mustard, honey, garlic powder & lemon juice. Then, add in the mashed chickpeas, celery, red onion, pine nuts, parmesan, basil and shredded chicken. Use a spatula to stir until evenly coated. If you prefer your chicken salad to be even moister, feel free to add an additional ¼ cup of greek yogurt. Taste and add more kosher salt & black pepper as needed.
