Got 3-day old leftover mashed potatoes? I have a delicious solution. Don’t waste them, make them into these crowd-pleasing appetizer.

You can add one or more eggs and adjust the grated cheese and seasoning depending on how many cups of potatoes you have left. These come together quickly, and can be pan-fried, air-fried, or baked in a hot oven. These are so good they are worth making fresh mashed potatoes for! However, refrigerated leftovers work best (and, studies have suggested that cooled potatoes have more resistant starch).
