Making the Turkey Meatballs:

1. Prepare the Meatball Mixture:
   • In a large mixing bowl, combine the ground turkey, breadcrumbs, Parmesan cheese, parsley, egg, garlic, onion powder, oregano, salt, and black pepper.
   • Mix the ingredients gently using your hands until well combined. Avoid over-mixing, as this can make the meatballs tough.
2. Shape the Meatballs:
   • Roll the mixture into small balls, about 1 to 1.5 inches in diameter. You should have approximately 18-20 meatballs.
3. Cook the Meatballs:
   • Heat 2 tablespoons of olive oil in a large skillet over medium heat.
   • Add the meatballs in batches, being careful not to overcrowd the pan.
   • Cook the meatballs for about 8-10 minutes, turning occasionally until they are browned on all sides and cooked through.
   • Remove the meatballs from the skillet and set aside on a plate.

Preparing the Tomato Sauce:

4. Sauté the Aromatics:
   • In the same skillet, add 2 tablespoons of olive oil over medium heat.
   • Add the chopped onion and sauté for about 3-4 minutes until translucent.
   • Stir in the minced garlic and cook for an additional 1 minute until fragrant.
5. Simmer the Sauce:
   • Add the crushed tomatoes, tomato paste, dried basil, oregano, red pepper flakes, salt, and pepper to the skillet.
   • Stir well to combine and bring the sauce to a gentle simmer.
6. Combine Meatballs and Sauce:
   • Carefully place the cooked meatballs into the simmering tomato sauce.
   • Cover and let the meatballs simmer in the sauce for 15-20 minutes, allowing the flavors to meld together.
7. Garnish and Serve:
   • Before serving, garnish with fresh basil leaves for an added touch of flavor and color.
