"Excellent use for leftover mashed potatoes! And, I always have all the other ingredients on hand. Don't let its looks fool you while it's cooking. It looked really thin, and I was afraid it was going to taste like warm milk, but it was delicious. I made it with leftover scallion mashed potatoes, put croutons on top, and served it with a salad. It was the perfect cool weather weekend lunch."
