01 - In a large mixing bowl, combine the boudin sausage (casings removed), chopped green onions, minced garlic, and parsley. Mix thoroughly until all ingredients are evenly incorporated.
02 - Scoop approximately 2 tablespoons of the mixture and roll into a compact, uniform ball. Repeat with the remaining filling until all the mixture is used.
03 - Place the all-purpose flour, beaten eggs, and breadcrumbs into three separate shallow bowls arranged in a breading line.
04 - Roll each boudin ball first in the flour, shaking off excess, then dip into the beaten eggs, and finally coat thoroughly with breadcrumbs. Arrange the breaded balls on a tray.
05 - Heat vegetable oil in a deep fryer or heavy-bottomed pot to 350°F. Fry the boudin balls in small batches until golden brown and crispy, approximately 3 to 4 minutes per batch.
06 - Remove the fried boudin balls using a slotted spoon or spider and drain on paper towels. Serve hot with Creole mustard or remoulade sauce on the side.
