We brought home a bunch of mashed potato leftovers from our Thanksgiving dinner. Fortunately, the Huffington Post provided this list of 19 things to do with mashed potatoes just in time for the holiday. I wasn't even sure which one to prepare as so many of them looked promising, so I began at the beginning and made the Cheesy Pancakes. It was pretty simple as the potatoes were already mashed all I had to do was add some shredded cheddar cheese and some chopped scallions and form them into patties. They cooked quickly and easily, and were quite tasty topped with some sour cream.
