In a medium saucepan place chicken and add broth to cover. Bring to a simmer, then cover, reduce the heat, and simmer gently until the juices run clear when pierced and the internal temperature of the chicken reaches 165℉, 15-20 minutes.
Meanwhile, in a blender combine tomato paste, chipotles, adobo sauce, chili powder, salt, and ½ cup chicken cooking liquid. Blend until smooth.
Shred chicken with 2 forks and toss with chipotle sauce.
In a medium bowl toss green and red cabbage, carrot, radish, green onion, lime juice, oil, and salt to taste.
Lay out wraps on a countertop and divide chicken between them. Top with slaw.
If desired, fold sides of wrap in, then fold bottom of wrap over filling and roll up tightly. Cut in half.
