Mashed Potato Pancakes

In large bowl, mix mashed potatoes, egg and Parmesan cheese. Season with salt and pepper and mix well to combine.

In large nonstick skillet, heat vegetable oil over medium-high heat. In batches, drop heaping tablespoonfuls of potato mixture into skillet, pressing with spatula to flatten slightly.

Cook until golden brown on bottom, about 3 minutes. Repeat with remaining potato mixture. Serve warm with sour cream as condiment, if desired, and a side dish of chunky apple sauce.
