01 - Combine ground turkey, grated onion, garlic, breadcrumbs, egg, parsley, oregano, salt, and pepper in a large bowl. Mix gently until just incorporated to avoid tough texture.
02 - Using damp hands to prevent sticking, shape mixture into 16–18 small meatballs, approximately 1.5 inches in diameter.
03 - Heat 1 tbsp olive oil in a large skillet over medium heat. Cook meatballs in batches, turning to brown on all sides, about 5–6 minutes total. Transfer to a plate and set aside.
04 - In the same skillet, add 1 tbsp olive oil, diced onion, and garlic. Cook until softened and fragrant, about 3 minutes.
05 - Stir in roasted red peppers and continue cooking for 2 minutes to develop flavor.
06 - Transfer pepper mixture to a blender. Add tomato passata, chicken broth, cream, smoked paprika, salt, pepper, and chili flakes. Purée until completely smooth.
07 - Return blended sauce to skillet and bring to a gentle simmer over medium-low heat.
08 - Add browned meatballs to the simmering sauce. Cover and cook gently for 15–20 minutes until meatballs reach internal temperature of 165°F.
09 - Taste sauce and adjust seasoning with additional salt and pepper if needed. Serve immediately, garnished with extra fresh parsley.
