For the Meatballs:

1. Preheat your oven to 375°F (190°C).
2. In a large bowl, mix together ground beef, breadcrumbs, egg, garlic powder, onion powder, Italian seasoning, salt, and pepper.
3. Take a small amount of the meat mixture and flatten it in your palm. Place a cube of mozzarella cheese in the center, then mold the meat around the cheese to form a ball. Repeat until all the meat mixture is used.
4. Place the meatballs on a baking sheet lined with parchment paper.
5. Bake for 20-25 minutes until cooked through and golden.

For the Spaghetti:

1. Cook spaghetti according to package instructions; drain and set aside.
2. In a large skillet, heat olive oil over medium heat. Add marinara sauce and bring to a simmer.
3. Toss cooked spaghetti in the sauce until well coated.
4. Serve spaghetti topped with cheese-stuffed meatballs. Use black olives to create spooky “eyes” on the meatballs if desired.
5. Garnish with fresh basil for a pop of color.
