Prepare the jackfruit: Drain, rinse, and gently massage the jackfruit pieces to shred them slightly.
Cook the onion: In a medium saucepan, heat avocado oil over medium heat. Add diced onion and cook until translucent, about 5-6 minutes.
Add jackfruit and spices: Stir in the jackfruit, garlic, chili powder, coconut sugar, paprika, cumin, and liquid smoke. Stir regularly to avoid sticking; if it dries out, add a splash of water. Cook for about 15 minutes.
Add BBQ sauce: Pour in the BBQ sauce, reduce heat, and let it simmer for 10-15 minutes until the jackfruit is tender and easily shreddable. Mash it with a fork for a pulled texture.
Prepare the slaw: In a large bowl, mix the slaw ingredients until fully combined and creamy.
Assemble the sliders: Scoop BBQ jackfruit onto rolls, top with slaw, pickles, and a dash of hot sauce if desired. Enjoy immediately!
