Irish Sausage (Banger's)

5 times in Ireland, staying in Bed and Breakfasts, can still smell the sausages cooking every morning. Have seen them sometimes at the HEB Central Market but not on a regular basis. They are delicious and different than any we eat in the States. Brands I remember are Galtee and Donnelly's. They are eaten at breakfast in Ireland but I'd eat them all the time. My Mom and Dad are from Ireland, and to be able to cook them for them when they come to visit would be great.
