Preheat oven to 450 degrees
Begin by trimming each piece of jackfruit, removing the hard parts and place them in a medium sized pan.
Once all chunks of jackfruit have been trimmed. Place them on the stove over a low-medium heat with a few drops or oil (or water) to cook them. Use the back of a fork to shred the jackfruit while it's cooking. Season with salt and pepper to taste.
Once the jackfruit has finished cooking, place it on a baking pan lined with parchment paper, creating an even layer. Cook in the oven for 20-25 minutes.
While the jackfruit is cooking, begin prepping the add-ons like the corn, cilantro, tomatoes, onions and avocados.
Rinse and drain the canned black beans. Place them in a medium-sized bowl and use a potato masher (or the back of a fork/spoon) to mash them. If the mixture begins to crumble, splash it with a few drops of vegetable broth to bind it together.
Once the jackfruit has finished cooking, remove it from the oven and transfer the mixture to a bowl. Pour BBQ sauce of your choice over the jackfruit and combine until all pieces are coated.
Start building your tostadas beginning with the mashed black beans, jackfruit, then veggies. Garnish with Cilantro. Enjoy!
