Prepare the jackfruit by draining and rinsing the canned jackfruit, and then separate the jackfruit with your hands or by smashing with a fork into a thread like texture.
Add all the spices, barbecue sauce, tomato paste, and vegetable broth into a large pot along with jackfruit. Bring the jackfruit up to a slow boil, and then reduce to medium heat and cook for 20 minutes.
In a separate medium bowl, combine the broccoli slaw, green onions, and rice wine vinegar. Allow to sit during the cooking process to soften the broccoli slaw.
Toast the bread of your choice.
Once your jackfruit has cooked, assemble your sandwiches. Serve with potato wedges or fresh watermelon!
