Place all ingredients in crockpot and cook on low for 6 hours. After it is done cooking take out 2/3 cup of juice and set aside. Then shred chicken. Add some of the juice if you would like or you can dump it.
Grab a tortilla and place a handful of lettuce down. Then scoop up some buffalo chicken and add it on top of the lettuce. Top with avocado and tomatoes. Drizzle with ranch dressing. If you like it extra spicy add some buffalo sauce drizzle.
