Peace:
Probably doesn't contain chocolate chips. Sorry, I'm being flip and the anolagy is, I think, a valid one. A "traditional" spaghetti sauce would be one based on tomatoes, with flavoring ingredients--oregano, garlic, onion, pepper, wine, mushrooms, basil, sugar, wine etc.-- apt to be available to an Italian cook. While modern food distribution may have made other ingredients available, I'd think that the sauce would stop being traditional when the taste of these "new" and "exotic" flavorings began to dominate the mix. Sure, a good cook might opt for a smidge of chili pepper, or possibly soy sauce, but while a heavy dose of these might conceivably make a tasty sauce, it would no longer be spaghetti sauce as we know it.
