Creating spaghetti and meatballs can be simple if you follow these steps:

1. Prepare the Meatball Mixture: In a large bowl, combine ground beef, ground pork, breadcrumbs, grated Parmesan, parsley, egg, minced garlic, salt, pepper, oregano, and basil. Mix until just combined.
2. Form Meatballs: Shape the mixture into meatballs, about 1 to 1.5 inches in diameter. Place them on a baking sheet.
3. Cook Meatballs: In a large skillet, heat a few tablespoons of olive oil over medium heat. Add the meatballs in batches, cooking until browned on all sides, about 5-7 minutes. Remove and set aside.
4. Prepare the Sauce: In the same skillet, add the marinara sauce and bring to a simmer. Return the meatballs to the skillet, cover, and let them cook in the sauce for about 15 minutes.
5. Cook Spaghetti: While the meatballs are simmering, cook the spaghetti according to package instructions in salted boiling water. Drain and set aside.
6. Combine: Once the meatballs are cooked through, gently toss the spaghetti with the marinara sauce and meatballs in the skillet.
7. Serve: Transfer to a serving dish and top with additional grated Parmesan cheese and fresh parsley if desired.
