I just use *gasp* canned apple pie filling!
I did use a frozen crust...but I wanted to use real apples. I should get me one of those apple slicers from King Arthur flour...then I'd just have to pare 'em and trim anything the slicer missed.
Or...even better, get one of those ones that clamp onto a table and slice and pare at the same time!
Luckily the rest of the recipe was easy peasy. If this comes out good, it will be my standard apple pie recipe forever.
