Add all sauce ingredients to a blender and blend until smooth. Set aside.
If making your own chicken: Add chicken breast to a sheet pan and coat in oil, salt, pepper, onion powder and garlic powder. Bake for 10-15 minutes, until a thermometer reads 165. Let chicken cool for 10 minutes and then Shred chicken using a mixer or fork.
Add shredded chicken, celery, red onion and green goddess sauce to a bowl and mix together until everything is all combined and chicken is fully coated in sauce.
Enjoy chicken salad on bread with your favorite toppings. I topped mine with pickled onions, sliced tomatoes, dill and flaky sauce. It also tastes great on its own or with crackers.
Notes
