1. Prepare Sauce and Add Chicken to Slow Cooker:

• Place the frozen skinless, boneless chicken breast halves directly into the insert of your slow cooker.
• In a medium bowl, whisk together the barbecue sauce, Italian salad dressing, packed brown sugar, and Worcestershire sauce until well combined.

2. Pour Sauce and Cook:

• Pour the prepared barbecue sauce mixture evenly over the chicken breasts in the slow cooker, ensuring the chicken is mostly covered.
• Place the lid securely on the slow cooker.
• Cook on the LOW setting for 6 to 8 hours OR on the HIGH setting for 3 to 4 hours. The chicken should be very tender and cooked through (internal temperature 165°F/74°C).

3. Shred Chicken and Combine:

• Once the cooking time is complete, the chicken should be fall-apart tender. You can shred the chicken directly in the slow cooker using two forks, pulling the meat apart into shreds.
• Alternatively, carefully remove the chicken breasts to a large plate or cutting board, shred them there, and then return the shredded chicken to the sauce in the slow cooker.
• Stir the shredded chicken thoroughly with the sauce in the slow cooker until all the chicken is well coated and moistened.

4. Serve:

• Serve the Zesty Slow Cooker BBQ Chicken hot. It’s classically delicious piled onto hamburger buns for pulled chicken sandwiches.
• Also great served over cooked rice, in salads, or used for tacos or nachos.
