01 - In a large mixing bowl, thoroughly blend the boudin sausage, green onions, garlic, and parsley until evenly mixed.
02 - Portion approximately 2 tablespoons of the mixture and shape each into a compact ball. Repeat for the remaining mix.
03 - Arrange the all-purpose flour, beaten eggs, and breadcrumbs separately in shallow bowls.
04 - Roll each ball first in flour, then dip into the beaten eggs, and finally coat well with breadcrumbs. Place prepared 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 for 3 to 4 minutes or until golden brown and crisp.
06 - Transfer with a slotted spoon to paper towels to drain excess oil. Serve hot with Creole mustard or remoulade sauce, if desired.
