I love pumpkin pie and anything made with apples, two of the most popular fall/autumn fruits.  I also like recipes using zucchini and yellow squash or spaghetti squash.  Not a lot of flavor in any of those squashes but they are great added to other dishes and it helps to stretch food if you have a bunch of kids!
