Preheat your oven to 350°F (175°C). Clean mushroom with a damp paper towel. Begin to cut off the bottom ends of the king oyster mushroom as that part is very tough. Cut off the tops and chop them up. You will want to keep this part as it's very tender.
Take your fork and comb through mushroom, creating a shredded texture. Transfer all your pieces to a baking pan, along with your shredded jackfruit. Be sure to use a big enough pan to separate the mushrooms from the jackfruit.
Sprinkle ½ teaspoon each of applewood smoked salt, garlic powder, on powder, and smoked paprika on top of both shredded king oyster mushroom and jackfruit. Toss to coat.
Next take some pieces of vegan butter and place it on top off the shredded king oyster mushrooms only, The butter helps "tenderize the mushrooms". I don't add butter to the jackfruit to dry them out and make them more "meaty." Bake in oven for 15 minutes. Once done, remove from oven and set aside. Keep oven on.
Grab a large mixing and add to it vital wheat gluten, nutritional yeast, 1 teaspoon each of applewood smoke salt, garlic powder, onion powder, and smoked paprika. Add ½ teaspoon of brown sugar to the flour batter mix together. Then add your baked jackfruit, oyster mushrooms, and vegetable broth to the bowl.
Begin to mix the ingredients together until liquid fully covers the flour, and quickly after begin to knead your mixture for a 1- 2 minutes. Do NOT over knead it. Just enough to fully combine the mushroom and jackfruit with the dough. Don't worry about if it isn't completely combined or perfect. Baking will help combine everything together.
Shape your dough into a rectangle loaf shape about 1 inch thick, and place it on of the same pan you used to bake your jackfruit and mushrooms. Top with Vegan BBQ Sauce and bake for 45 to 50 minutes. Once done, allow to cool for 5 minutes. top with more Vegan BBQ Sauce and cut horizontally into strips. Serve with some vegan potato salad, vegan baked beans, and vegan coleslaw!
