My husband was given a bag of peaches by a friend, but neglected to bring them home from his office for about 5 days. By the time I got them they were very close to being spoiled. I salvaged what I could but didn't have enough for a full size pie. So, I peeled & thinly sliced a large gala apple I had and added that to the peaches. I added sugar, cornstarch, & cinnamon, and made a 2-crust pie. It turned out really good. It actually tasted more like apple pie, even though there was more peach in the filling than apple.
