Cheesy Tuna Potato Cakes

One of my favorite side dishes is mashed potatoes, especially when the weather starts to cool down. I almost always make extra because it’s easy to turn them into potato cakes or bread or something the next day.
Or in this case, a full meal in one go. A can of tuna amps up the protein, and makes your mashed potatoes a meal. When served with a green vegetable, it actually makes a somewhat elegant meal. With a can of tuna — who would have thought?
The beauty of this is that you can flavor them however you like with whatever you have on hand. Chopped scallions, bacon, or whatever you have works. In this case, sharp cheddar. I like to make these using a round cookie cutter. It makes them uniform in size, and you can pack in the potato mixture so that it stays together nicely when you cook it. This is the perfect way to use up leftovers.
