Filling: Steam tempeh for 20 minutes, then either shred or dice finely. Stir into the remaining ingredients in a large saucepan. Bring to a simmer & cook for 10 minutes, stirring occasionally. Remove from heat & set aside to cool.
Crust: Pre-heat oven to 400F. Combine all the pie crust ingredients until a soft dough is formed. Add more juice if necessary. Divide into 2 pieces, one slightly larger than the other. Place larger ball of dough onto a lightly floured surface & roll into a 9" circle. Place into an 8" pie plate.
Spoon filling into the pie crust. Roll out remaining ball of dough & place on top of the filling. Seal & crimp the edges. Bake for 10 minutes & then reduce the heat to 325F & bake until the crust is lightly browned, about 30 minutes. Cool & serve.
