Barbecue Slawpy Jacks

Rinse jackfruit under cold running water; drain and pat dry with paper towels.

Heat oil in a large skillet over medium-high. Add jackfruit, and stir to break up fruit. Cook, stirring occasionally, until lightly browned in spots, about 5 minutes. Add barbecue sauce, and cook, stirring occasionally, until mixture begins to caramelize, about 2 minutes. Remove from heat.

Toss together green cabbage, red cabbage, carrot, and scallions in a medium bowl. Whisk together mayonnaise, vinegar, mustard, sugar, salt, and pepper in a small bowl; drizzle over cabbage mixture, and toss until coated. Divide jackfruit mixture among bottoms of buns; top with slaw, and cover with tops of buns.
