Combine the tomatoes, carrots, bell pepper, cilantro, scallions, peanut butter, soy sauce, chile powder, cocoa powder and Chinese five-spice powder in a 6-quart slow cooker and stir to combine. Add the turkey and turn to coat. Cover and cook on low, 8 hours.
Remove the turkey and transfer to a large plate; shred the meat with 2 forks, discarding the bone. Return the shredded turkey to the slow cooker and stir to coat.
Warm the tortillas in a dry skillet or in the microwave. Serve the turkey in the tortillas and top with more cilantro and scallions.
