Swap beef for turkey and you get meatballs that are just as satisfying but way leaner. Toss them in marinara for a high protein dinner the whole family will ask for again.
Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper for easy cleanup.
In a large mixing bowl, gently combine ground turkey, egg, whole wheat breadcrumbs, Parmesan, onion, parsley, garlic, oregano, salt, and black pepper. Do not overmix to ensure tender meatballs.
Portion the turkey mixture into 16 evenly-sized balls, about 1½ inches each, and place them spaced apart on the prepared baking sheet.
Bake the meatballs on the center rack for 18-20 minutes, or until lightly browned and cooked through (internal temperature should reach 165°F).
Meanwhile, heat marinara sauce in a saucepan over medium-low heat. Once meatballs are cooked, transfer them gently into the marinara. Simmer for 5 minutes over low heat to meld flavors.
Serve hot, garnished with extra parsley or Parmesan if desired.
