Mashed Potato Pancakes

I know I'm probably starting to sound like some kind of mashed potato freak because I talk about them quite a lot. I promise I'll stop after this, but I figure you might have some extra mashed potatoes laying around your fridge after Thanksgiving and need something to do with them. Last night I made some pancakes with my leftovers. They were tasty and went well paired up with a yummy salad (greens, toasted walnuts, cranberries, red onion and a balsamic vinaigrette) and some leftover soup. I had some corn in the same container, so I mixed it right into the pancakes. You could also make some of the gravy from yesterday's entry to pour on top.

Mashed Potato Pancakes
2 cups cold mashed potatoes
1 egg slightly beaten
1/4 c butter or vegan margarine
1/2 c flour for dredging
salt and pepper to taste
1 small onion minced (optional)

1. Mix the potatoes, onion and egg together and form into 6 lean patties or 4 fatter ones. (I didn't include the onion. I was afraid it wouldn't cook enough)
2. Heat the butter in a skillet over medium heat. Dredge the patties on both sides in the flour.
3. Sautee in the pan, browning both sides and making sure the patties are heated through.
