Thanksgiving Leftover Potpie

I made a butternut squash crust with wheat flour in my food processor with the following approximate ingredients:
1.5c cooked squash
1.5 c flour
1 c almond milk
1 tbsp butter
1 tsp salt
Basically, it turned out like a spoon bread rather than something you could roll out.  So I just spooned it into the pan.

Filling - pretty much whatever you have leftover
Turkey
Cooked potatoes
Carrots
Some more squash
Onion

I made the sauce out of leftover gravy 1:1 with chicken broth, but if you are out of gravy, you could just do a broth/flour/herb sauce.

I topped it with spooned dough and baked it at 400 for 25 minutes.
