01 - In a large bowl, combine Cajun boudin sausage, green onions, garlic, and parsley. Mix thoroughly until the mixture is homogeneous.
02 - Portion approximately 2 tablespoons of the filling and shape into compact balls. Repeat with the remaining mixture.
03 - Place flour, beaten eggs, and breadcrumbs in three separate shallow bowls.
04 - Coat each ball in flour, dip into egg, and then roll in breadcrumbs. Arrange breaded balls on a tray.
05 - Heat vegetable oil in a deep fryer or heavy-bottomed pot to 350°F. Fry boudin balls in batches for 3 to 4 minutes, until golden and crisp.
06 - Remove with a slotted spoon and drain on paper towels. Serve warm with Creole mustard or remoulade sauce if desired.
