01 - In a large mixing bowl, combine the boudin sausage, green onions, garlic, and parsley. Mix thoroughly until all ingredients are evenly incorporated.
02 - Scoop approximately 2 tablespoons of the mixture and shape into a compact, uniform ball. Repeat with the remaining mixture until all filling is used.
03 - Place the flour, beaten eggs, and breadcrumbs into three separate shallow bowls, arranged in a breading line from left to right.
04 - Roll each boudin ball in the flour, shaking off excess, then dip into the beaten egg, and finally coat evenly with breadcrumbs. Place 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 batches, being careful not to overcrowd, until golden brown and crispy, about 3 to 4 minutes per batch.
06 - Remove the fried boudin balls with a slotted spoon or spider and transfer to paper towels to drain excess oil.
07 - Serve hot alongside Creole mustard or remoulade sauce for dipping.
