Could do some substitutions like kiefer- Leftover Mashed Potato Puffs. They’re combined with eggs, sour cream, cheese and chives then baked in a cupcake pan until golden and crusty with creamy middles. They don’t taste like leftovers.
With fluffy potato centers and golden-crisp bread coating, these loaded mashed potato balls are a delicious party appetizer or any time of the day snack the whole crowd will love. (Christmas Appetizers For A Crowd)
