In a large bowl, combine ground chicken, cottage cheese, Parmesan, breadcrumbs, garlic powder, and onion powder.
Roll mixture into meatballs.
Heat a greased skillet over medium heat. Add meatballs and cook, flipping halfway through, until the internal temperature reaches 165°F.
Pour in pasta sauce and add spinach.
Reduce heat to low and let simmer until the spinach wilts and the sauce is heated through.
