Pigs in a blanket (also pigs in blankets) is a variety of different sausage-based dishes. Smaller versions of the dish are commonly served as an appetizer or hors d'oeuvre, sometimes with a mustard or aioli dipping sauce, or are accompanied by other foods during the main course.
In the United Kingdom the term is commonly used for small sausages (usually cocktail sausages) wrapped in bacon; in the United States it typically refers to hot dogs wrapped in croissant pastry.
