Prepare the stuffing for your tofu roast's filling. Use vegan stovetop stuffing or cauliflower stuffing to make it gluten-free.
Make the binding mixture
In a large measuring container, add 3/4 cup chickpea flour, then slowly stir in 1 cup vegan broth and mix it until smooth. Add 3 tablespoons of nutritional yeast, 2 tablespoons of oil, 1 tablespoon of Bragg's Liquid Aminos, 4 teaspoons of poultry seasoning, 3/4 teaspoon of salt, 1/2 teaspoon of garlic powder, and 1/2 teaspoon of onion powder, then stir well again and let it sit for 5 minutes.
Blend the tofu and the binder
Drain 2 (16 oz) blocks of high-protein tofu, break them into pieces, and put them into a large food processor. (If you are using extra firm tofu, use 2 1/2 (14 oz) packages and press them very well to get out all possible liquid.)
Once the broth and chickpea mixture has sat for at least 5 minutes, pour it over the tofu in the food processor. Blend on high for about 2-3 minutes, scraping the edges frequently until the mixture is very well incorporated.
Assemble your tofu turkey
Oil the bottom of a baking dish, then spoon out half of your tofu mixture into the dish and flatten it out smoothly.
Place 1 1/2 cups of cooked stuffing mounded up in the center of the dish leaving about an inch around the edges.
Cover the stuffing with the remaining tofu mixture, then smooth it out with a silicone spatula.
Make the basting liquid
Mix 1/2 cup broth, 2 tablespoons oil, 1 teaspoon Bragg's Liquid Aminos, 1 teaspoon oregano, and 1/4 teaspoon black pepper, and pour about half of the mixture over the tofu turkey.
Bake the tofu turkey
Bake uncovered at 375°F (190 °C) for 45 minutes, then remove it from the oven and baste with the remaining basting liquid. Return it to the oven for an additional 40 minutes.
Allow the tofu turkey to cool for about 15 minutes before slicing.
Notes
You can eat this tofu turkey on the first day, but I think it tastes even better after it sits overnight, allowing the flavors to blend. For this, you have 2 choices...
You can prepare the tofu mixture a day ahead and store it covered in the fridge for up to two days until you are ready to baste and bake it.
Fully bake the "turkey" a day ahead, then brush it with a little oil and reheat it in the oven at 350°F for about 20-25 minutes, until warm.
I know that you bake this roast for a long time, and it may look done, but please bake it for the full 1 hour and 25 minutes. It is a large loaf, and the chickpea flour needs to bake fully, or it will have a funny aftertaste.
Feel free to cut the recipe in half and bake it in a loaf pan instead.
