Next time you mash potatoes, make extra so you can make this tasty side dish the following day. It is really simple and it looks great too. The recipe calls for leftover mashed potatoes. The potatoes should be prepared simply, as I do, with just some butter, milk, salt, and pepper......and not too much moisture. If you double the recipe you will have enough for 8 people for your next barbecue. Baked beans, corn on the cob, and cole slaw would all go well with this. I believe this recipe would be fantastic as you topper for a Shepherd's Pie. I'm going to try that next time I make them.
