01 - Combine ground turkey, grated onion, garlic, breadcrumbs, egg, parsley, oregano, salt, and pepper in a large bowl. Mix gently until just combined to avoid overworking the meat.
02 - Form mixture into 16 to 18 small meatballs using damp hands to prevent sticking.
03 - Heat 1 tbsp olive oil in a large skillet over medium heat. Cook meatballs in batches, turning to brown on all sides for about 5 to 6 minutes total. Remove and set aside.
04 - In the same skillet, add 1 tbsp olive oil, diced onion, and garlic. Sauté until softened, approximately 3 minutes.
05 - Add roasted red peppers to the skillet and continue sautéing for 2 minutes.
06 - Transfer the mixture to a blender. Add tomato passata, chicken broth, cream, smoked paprika, salt, black pepper, and chili flakes. Blend until completely smooth.
07 - Return sauce to the skillet and bring to a gentle simmer.
08 - Add browned meatballs to the simmering sauce, cover, and cook gently for 15 to 20 minutes until meatballs are fully cooked through.
09 - Taste and adjust seasoning as needed. Serve hot, garnished with additional fresh parsley.
