I had a couple of boxes of Seitan I wanted to use up, so came up with this recipe. I used as many organic ingredients as I could. I think it just tastes better. I used a 91/4 round x 2 3/4 inch casserole dish. This dish can hold about 3 quarts. You can make any good single pie crust for this and top the pie. I don't do a bottom crust, but if you want to it will change the cooking time for this pie.
