01 - In a large bowl, combine ground turkey, egg, Parmesan, breadcrumbs, garlic, parsley, oregano, salt, and pepper until just blended.
02 - Form the mixture into 16 small meatballs, approximately 1½ inches in diameter.
03 - Heat 1 tablespoon olive oil in a large skillet over medium heat. Add meatballs and cook, turning occasionally, until browned on all sides, about 6 to 8 minutes. Remove and set aside.
04 - In the same skillet, heat 1 tablespoon olive oil. Sauté onion over medium heat until translucent, about 3 to 4 minutes. Add garlic and cook for 1 minute.
05 - Stir in crushed tomatoes, basil, oregano, salt, pepper, chili flakes, and sugar. Bring to a gentle simmer.
06 - Nestle meatballs back into the sauce. Cover and simmer for 15 minutes, or until meatballs are fully cooked.
07 - Spiralize zucchinis into noodles, then pat dry with paper towels to remove excess moisture.
08 - Heat 1 tablespoon olive oil in a separate large skillet over medium-high heat. Add zucchini noodles and sauté for 2 to 3 minutes until tender. Season with a pinch of salt.
09 - Plate zucchini noodles, top with turkey meatballs and spoon marinara sauce over. Garnish with extra parsley or Parmesan if desired.
