Start by cutting the center out of your bread. Pull apart the center, (after it is removed), making bite size pieces. Set aside.
Place your cream cheese, sour cream, chicken, cheese, bacon, garlic powder, onion powder, ranch seasoning, and Worcestershire Sauce in a large mixing bowl.
Mix on high until combined.
Spoon mixture into the center of your prepared bread bowl.
Top with leftover bacon, shredded cheese, and chopped green onions.
Surround with your bread bites, and celery. Serve.
