What is the ideal fake turkey substitute for a vegan Thanksgiving?
I always make a tofu turkey by blending tofu with herbs and flavorings and then draining over night in a colander dressed with a kitchen towel. The next day I shape the tofu info a turkey shape with stuffing inside, wrap it in a soaked yuba sheat and bake it in the oven, brushing with butter and marinade occasionally. 

This "turkey" will not have the texture of turkey meat but it will be carvable. 

The skin will have a texture similar to turkey skin.  

The flavor of this "turkey" (I use a lot of sage, light miso and poultry seasoning) is very traditional and goes well together with above mentioned gravies and stuffings.

When brushed with enough marinade and butter it will be moist if a little crumbly. 

I spent about 10 € on the tofu (6 blocks of 450 g each), 2.50 € on the skin and 5 € on the herbs. If you have buy seasoning, miso, etc, it will cost more.
