Place chicken breasts in crock pot over low heat. Pour BBQ sauce over the chicken. If I have onions on hand, I will put a few slices on top of the chicken. Cook for 6 hours, or until the chicken shreds easily. Can also cook on high for 3-4 hours. Shred chicken and remove any fat.
For the dressing: Combine ranch dressing, cilantro, lime and tomatillo in a blender. If you like it spicy, you could throw half a jalapeno in there. Refrigerate for at least 30 minutes.
Place desired amount of lettuce on your plate. Then add a few spoonfuls of chicken and black bean salsa. Pour on dressing and top with tortilla strips.
