Drain and rinse the jackfruit through a colander. Shake out any excess water. Lay the jackfruit on a paper towel and pat dry. Using your fingers, press the jackfruit chunks and the base to fan out, pushing it into large shreds. See this video for a visual. Set aside. Next make the mango avocado salsa by mixing together the avocado, mango, jalapeño, lime, cilantro, and salt. Taste and adjust seasonings.
Add avocado oil (or oil of choice) to a large skillet. Place over medium heat. Once the oil is hot, add the jackfruit and sauté, stirring often, for about 3 minutes until lightly browned. Add BBQ sauce and continue sautéing until most the liquid absorbs into the jackfruit. Remove from heat.
Set your oven to broil and lightly broil your ciabatta rolls, ensuring they don't burn. This will just take 2-3 minutes.
To assemble the sandwiches, place about ¼ cup of jackfruit pulled pork on top of a ciabatta bun. Add about 2 heaping tablespoons of Avocado Mango and top with the bun. Serve immediately.
