First of all, waffles are usually sweet. But with cheddar, herbs, spices, and breadcrumbs, these savory bites are sure to excite. Then, the flavorful gravy seals the deal. Is this the best way to have leftover mashed potatoes?

Mashed Potato Cakes Recipe

Think of these delicious mashed potato cakes from Carrie of Eating On A Dime as the base for all sorts of toppings like sour cream and chives, apple sauce, or even brisket.

Leftover Potato Gnocchi
