Which dish is famous for a 1-pound meatball option on the menu?

The dish famously associated with a 1-pound meatball option is Spaghetti and meatballs. This classic Italian-American dish features spaghetti served with a rich tomato sauce complemented by large, hearty meatballs. The inclusion of a 1-pound meatball distinguishes this item on the menu, offering a substantial and signature component that aligns with the restaurant's identity and appeal to guests seeking a filling and traditional meal. The doughiness of the spaghetti, paired with the sizable meatball, creates a satisfying dining experience that is particularly attractive to those looking for a generous serving of comfort food.

The other choices do not emphasize meatballs in the same way; for instance, Fettuccine Alfredo is primarily known for its creamy sauce and pasta. Lasagna consists of layered pasta and cheeses without a specific focus on meatballs. Penne Arrabbiata is a spicy pasta dish that highlights a different sauce entirely, lacking any association with meatballs. Thus, the recognition and popularity of the large meatball uniquely categorizes Spaghetti and meatballs as the correct answer.
