Prepare Pulled Jackfruit: Drain jackfruit and pat dry. Partially shred jackfruit chunks into smaller pieces. In a sauté pan, heat olive oil over medium heat. Add jackfruit and sauté for five minutes. Add BBQ sauce and water to pan and stir to evenly coat jackfruit. Cover pan and simmer on medium-low heat, 20-25 minutes, stirring occasionally and pulling jackfruit apart as it becomes tender.
Prepare Tangy Cole Slaw: While jackfruit cooks, in a large bowl, toss cabbage blend with mayonnaise and apple cider vinegar to coat. Season with salt and pepper to taste and set aside.
Prepare Sandwiches: Place a scoop of pulled jackfruit on the bottom of a bun. Top with diced onions, coleslaw, and bun top. Eat and repeat until satisfied!
