Chili dog
Chili dog is the generic name for a hot dog served in a bun and topped with some sort of meat sauce, such as chili con carne. Often other toppings are also added, such as cheese, onions, and mustard. The style has many regional variations in the United States. Some of these have specific sauce ingredients, types of hot dogs, or types of buns. They are referred to regionally under region-specific names.
