In a large bowl, combine beef with breadcrumbs, Worcestershire sauce, parmesan, egg, garlic, salt and pepper flakes.
Mix until just combined and form into 16-18 balls.
In a large pot over medium heat, add 1 tbsp oil. Add meatballs and cook, turning occasionally, until browned on all sides, about 10 minutes.
Remove meatballs and reserve on plate.
Add the remaining olive oil and onion and saute until onion is translucent.
Add crushed tomatoes. Season with salt and pepper and bring to a simmer.
Add the meatballs back into the pot, cover and simmer until the sauce has thickened, 8-10 minutes.
In a separate large pot boil water. After water boils put in spaghetti noodles and let it cook for 5-10 minutes or until noodles are soft and ready to eat.
Pour spaghetti sauce with a good helping of helping of meatballs. Sprinkle with Parmesan cheese and enjoy! Best served with garlic bread!
