vegan curried vegetable pot pie

For added inspiration, the hosts of Dark Days Challenge are posing smaller themed challenges (one-pot meal, valentine sweets, vegetarian meal, breakfast) within the larger challenge of eating local, sustainable food in the middle of winter.  This week's themed challenge was to create a one-pot meal and because I love my cast iron skillet and I love that you can pan fry with it or bake with it, I decided to do both with it.  I also decided to use coconut milk which is a very non-local choice, but it makes this dish vegan. Who knows, if I did the math, it could possibly have less of an environmental impact than dairy.  Has anyone done the math?

Filling Ingredients:
2 potatoes, diced
1 red onion, diced
3 cloves garlic, minced
4 oz. mushroom
1 c. frozen peas
1 c. frozen corn
black garbanzo beans, boiled
canola oil (not local)
salt (not local)
black pepper (not local)
1 T. sweet curry powder (not local)
1 T. hot curry powder (not local)
dash of apple cider vinegar (not local)
1 (14oz.) can coconut milk (not local)

Dough Ingredients:
whole wheat flour
cold water
canola oil (not local)
ground flax seed (not local)

Unfortunately, I ended up having a few extra dishes to clean up: a small pot and mixing bowl.  The small pot was for boiling the garbanzo beans but that was an easy clean.  I had to use a mixing bowl to mix the dough.  I also used the mixing bowl to pour out the cooked filling while I laid out a bottom crust though you could easily go with just a top crust.
