Place the 1 pound ground chicken in a large bowl together with the beaten 1 large egg.
In a small bowl combine the seasonings( 1 1/2 teaspoon dried oregano, 1 teaspoon dried basil, 1/2 teaspoon cayenne pepper, 1 teaspoon kosher salt, 1 teaspoon garlic powder, 1 teaspoon onion powder) with the 1/4 cup breadcrumbs and add them to the meat.
Mix well to combine and form into small meatballs. Dredge the meatballs into the 1/4 cup all-purpose flour.
Heat 1/4 cup olive oil in a large pan over medium heat. Cook the meatballs for 2-3 minutes per side, or until golden and cooked through. Transfer the meatballs to a plate and cover to keep warm.
To the oil from the pan add the 3-4 garlic cloves (minced) and cook for 30 seconds.
Add the juice of 2 lemons, zest of 1 lemon, 2/3 cup capers, and 2 tablespoons finely chopped parsley. Simmer for 3-4 minutes to allow the flavors to meld.
Return the meatballs into the sauce together with the parsley and continue to simmer for 3-4 minutes, to heat up and help the sauce thicken even more.
Serve over cooked spaghetti and enjoy!
Notes
You can prep the meatballs ahead of time and refrigerate them for up to 2 days. The cooked meatballs and sauce keep well in the fridge for 3 days.
Freeze leftovers in an airtight container for up to 3 months—just thaw and reheat gently on the stove.
You may use ground turkey instead of ground chicken if you prefer.
