Place chicken in slow cooker.
Toss cut up onions over top of the chicken.
Combine brown sugar, Italian dressing and ½ of the BBQ sauce together in a medium size bowl. Whisk until smooth. Add garlic, honey, and spices. Whisk until combined. Pour over chicken and onions.
Place lid on slow cooker. Cook on low for 6 to 8 hours, or until chicken is tender enough to pull apart with forks.
Use forks to shred the chicken, or use a hand mixer with beaters to shred the meat. This technique works beautifully for shredding pulled meats.
Add remaining sauce to the slow cooker with the meat, and cook just until it heats up. I usually heat it all up in a cast iron pan for a few minutes to really bring it all together and save time. You do whatever works for you. Once it's hot and well combined you're good to go. Time to chow down.
Place on slider buns or hamburger buns. Eat it plain or with a slaw. Your choice.
Serve with a big old Pulled BBQ Chicken loving smile!
