Made this pie in about 40 minutes using the leftover "taco meat" from last night, some frozen veggies, mushrooms, homemade miso gravy and instant mashed potatoes (sorry, it's a weekday!). The miso gravy is so good. Find the recipe here. Make sure to substitute vegan margarine for the butter. I also added a little veggie broth as well. Can't wait to eat this when I get home from work!
