Pistolette
A pistolette is either of two bread-based dishes in Louisiana cuisine. One is a stuffed and fried bread roll (sometimes called stuffed pistolettes) in the Cajun areas around Lafayette. The other is a type of submarine shaped bread about half the size of a baguette that is popular in New Orleans for Vietnamese bánh mì and other sandwiches. In France and Belgium, the word pistolet refers to a round roll.
