Which regional hot dog style is topped with chili, slaw, onions, and mustard? The answer is Carolina style.

A Carolina-style hot dog is associated with North Carolina and South Carolina, especially the Carolinas’ Coastal Plain and Piedmont regions. Its defining combination is chili, cole slaw, chopped onions, and mustard. The toppings create a contrast of savory meat sauce, crisp or creamy slaw, sharp onion, and tangy mustard.

There is some local variation in the formula. In certain places, mustard is added as a fourth topping; elsewhere, it may replace the slaw. That variation does not make the listed answer unclear, because “Carolina style” is the established regional label for this family of toppings.

The name can cause confusion because regional hot-dog labels are not always literal descriptions of where a style was invented or where it is exclusively sold. Carolina-style toppings also appear on hamburgers, and North Carolina stands commonly pair the style with red-colored hot dogs. Seattle style is instead known for cream cheese and grilled onions, while a generic chili dog lacks the Carolina combination of slaw and onions.
