I have made four turkey dinners this month, needless to say I have had a lot of leftover mashed potatoes in the fridge! They are never really the same when reheated, so it was time to turn them into something totally different.
Since the mashed potatoes are already seasoned, they are the easiest thing to turn into soup. In fact, regardless of what you have added to them flavor wise, it's most likely going to work. Potatoes are versatile that way.
Anyway, I had this simmering on the stove and my oldest son insisted on having it as an after school snack, he loved it. It's delicious and naturally thick. It takes only minutes to make since the potatoes are already cooked and you're really just heating them through.
This will be a great way to use up holiday leftover mashed potatoes or you just might find yourself making extras just so you have leftovers. Either way, enjoy this dish.
