Spray your slow cooker with non stick cooking spray.
Place your chicken breasts in the slow cooker.
In a bowl, combine your Worcestershire sauce, bbq sauce, teriyaki sauce, lemon juice, garlic salt and minced garlic, until well combined.
Pour the mixture over your chicken breasts.
Cook on low for 6 hours.
After 6 hours, shred your chicken, and place back in the slow cooker to keep warm while you prepare your Cole slaw.
To make Cole slaw, combine your mayonnaise, apple cider vinegar, sugar, mustard, and pepper, in a large bowl.
Add your shredded cabbage.
Place a scoop of the chicken on your bun and top with a scoop of Cole slaw.
Top with extra barbecue sauce or teriyaki sauce if desired, and serve.
