One of my favorite things after a big party or celebration is the leftovers. Most of the time, we simply heat them up and eat the same dish again, but sometimes we like to get creative. When it comes to mashed potatoes, we always prepare a lot because there are always leftovers. Mashed potatoes taste delicious the day they're made, but usually feel a little dry the next day. One delicious way to reuse them is in potato pancakes. This dish can be prepared in half an hour and is very inexpensive.
