This is spaghetti dish called “Napolitan” I cooked. “Napolitan”is probably nothing to do with the town in Italy. Its origin is...I don’t know. I will find out about it someday. Anyway most Japanese people like Napolitan! It is seasoned by ketchup and tomato paste with cooked (fried?)onion and bacons or sausage. The trick to making this dish delicious is not to make it al dente‼︎ Boil the spaghetti a little softly to let the taste blend in.
