Pour ginger ale, half a bottle of your favorite barbecue sauce, onions, garlic, salt, and pepper into a slow cooker and whisk together. Place the chicken into the cooker. Cook for 12 hours on LOW.

Drain the liquid, reserving about a cup. Pull the chicken with two forks and add it back to the slow cooker with the reserved liquid and the other half of the barbecue sauce.

Make some sandwiches with your choice of "fixins" and enjoy!
