A first in my house! Store bought mashed potatoes. Simply Brand of course. I had left over hand pie filling in the freezer, which had cubed potatoes. I made a guinness gravy and added the pie filling. I took the store bought potatoes and added green onions,cheese, sour cream and some cabbage that I cooked in bacon fat. So fancy colcannon. Now we have double potato! I used my pastry silpat that has measures and spread the potatoes mixture out to fit the fan size and topped the filling. Brushed it with butter and baked. Ta-Da Shepherd’s Pie Oh My!!
