Serving Suggestions

Just like bubble and squeak,leftovers make this dish is a full and satisfying meal in itself! Some bread or a salad is all you need to fill out this satisfying stick-to-your-ribs entrée. Irish soda bread or rye bread are great choices.

Keep the Irish theme going by serving green beer to the adults, or green ginger ale for the kids.
