You can always enjoy this as a side dish with main dishes like Roasted Chicken, Honey Guinness Chicken Drumsticks, Corned Beef Brisket, Beef Brisket, steaks, and many more! You can use Colcannon in Bangers and Mash instead of the classic mashed potatoes. When you have leftover Colcannon, you an easily make some mashed potatoes cakes with it!
