Place chicken breast in the slow cooker. In a small mixing bowl whisk together wing sauce, garlic powder, and dressing. Pour over chicken in the slow cooker.
Cook on high for 3-4 hours or on low for 5-6 hours. Cook until chicken is tender and can be shredded with a fork.
Shred chicken and serve on a slider bun topped with blue cheese crumbles. *If you don't like blue cheese you can top with shredded cheese or add more dressing to the top.
