Drain a block of high-protein tofu and pat it dry with a paper towel to remove any excess liquid. Then use a mandoline or peeler to slice the tofu into thin shavings and place them into a shallow container.
Combine vegetable broth, Bragg's Liquid Aminos, liquid smoke, smoked paprika, garlic powder, and a dash of cayenne pepper to make a tofu marinade. Stir well, then pour it over the shaved tofu and allow it to sit for at least 10 minutes or up to 2 days in the fridge.
Grease a sheet pan with 2 tablespoons of olive oil, then pour the shaved marinated tofu onto the pan, including the marinade liquid.
Spread the tofu out evenly, then bake at 400°F (204°C) for 30-35 minutes, flipping after 15 minutes.. Cook until the excess liquid has been absorbed and the edges of the tofu begin to get crispy.
Use immediately or store in the fridge for up to 5 days for use on sandwiches and wraps.
Lightly butter one side of your bread. Place the buttered side down on the skillet, top with the baked shaved tofu, and drizzle with spicy tahini sauce or your condiment of choice. Then, place the other piece of bread on top, buttered side up.
Grill the sandwich for about 3-4 minutes on each side until golden brown, and serve hot.
Notes
You can prep the tofu up to 2 days ahead and let it sit in the marinade until you are ready to bake it.
Watch the shaved tofu closely towards the end of cooking, as it is sliced so thin that it can burn quickly.
If you don't have a mandoline, a standard vegetable peeler will work well for slicing the tofu into super-thin slices.
The shaved tofu will make enough for about 4-5 sandwiches, depending on how thick you make them. You can store the leftover tofu deli meat in the fridge for up to 5 days and use it on sandwiches throughout the week.
If you want to make this sandwich oil-free, you can bake the tofu on parchment paper and serve it on toast or plain bread instead of grilling it.
