Pre-heat oven to 350 F (177 C).
In a small bowl, whisk together ground flax and 9 tablespoons of water. Allow to sit for at least 5 minutes; this creates the flax “egg” goo.
In a blender, combine pumpkin puree and silken tofu until very creamy.
In a stand-mixer/with a hand-mixer, combine the pumpkin/tofu mixture (from the blender) with sugar, and vanilla. Once well mixed, slowly add in the dry ingredients for the filling (salt, pumpkin pie spice, flour, and cinnamon).
For the crust, in a medium bowl, mix together (I do this part by hand with a spatula) the TVP, flax “egg” goo, 2 tablespoons of your pie filling, cinnamon, brown sugar, salt and flour.
Take the crust “dough” and spread it evenly onto your pie pan with a spatula. Press it down.
Bake just the crust for 5 minutes.
Take the crust out of the oven, add the pie filling to it.
Bake for about 30 minutes, until the top begins to brown.
Allow to cool before you cut it (which is not what I did lol).
