Here's my favorite way to use up left-over mashed potatoes. If your mashed potatoes are flavored with garlic, onions, etc. it's all the better. Measurements are approximate since I usually throw this together to use up leftovers in the fridge. If my potatoes are plain, I have been known to add a little chicken bouillon to give them more flavor. Serving size may vary- my two year-old DD and I share one of these for lunch. This definitely is not a "diet" meal, but, it's delicious!
