This is the perfect comfort food for cold days. To make it vegan, substitute non-dairy ingredients for dairy. Leftover filling makes a great lunch! If you want to make mashed potatoes from scratch, you will want at least 4 cups when you are through.
This is a wonderful twist on the traditional apple pie - great for fall! It calls for Pippin apples, but I usually use a combination of several kinds. Occasionally I add a bit of cinnamon, too!
