My sister Debbie is a few years older than me (8) so we didn't really "grow up" together, she was always a few stages ahead of me. I had always admired her strength, creativity and ability to get s**t done but it wasn't until thanksgiving 15-20 years ago that I found out she was basically a genius at life. Instead of showing up at our mother's with Tupperware for leftovers she came bearing a half dozen frozen pie crusts. She probably said "f*** Tupperware" ( she swore a lot, she had 4 kids) "I'm making thanksgiving pies and freezing them, Nobody wants to haul all that food out every time you make a plate!" Genius. There was no Pinterest back then kids.
It's super easy and self explanatory but here's how I do it.
I had two extra pie crusts and put them in 8" cake pans (my pie plates were busy)
Then a good amount of gravy and the chunkier veggies I had, roasted butternut and Brussel sprouts.
Wrap them nice and tight in plastic wrap and then foil and stick them in gallon size ziplock bags and freeze
