In a large bowl, combine ground chicken, breadcrumbs, salt, pepper, parsley, garlic, and egg. Scoop mixture into 1-in meatballs and place on a baking sheet.
In a large skillet over medium-high heat, heat olive oil and butter and swirl pan to evenly coat. Add meatballs to pan and sear on all sides, turning occasionally with a tongs until meatballs are golden brown.
Add green goddess sauce and kale to pan with meatballs and bring to a simmer over medium-high heat. Reduce heat to medium-low, cover pan, and allow to simmer 5-8 minutes until meatballs register 165F and kale is tender, stirring occasionally.
Top meatballs with additional parsley and serve warm over pasta. Enjoy!
