You take frozen chicken breasts and literally throw them in the crock pot. (Ha! Who else thinks crock pots are hilarious and redneck but loves them anyway?) Set temp on low or high, depending on how fast you need your chicken, and move on with your day. Take kids to school, work out, put your feet up. Do what you need to do.
Four to six hours later. Ta dah.... Tender juicy chicken. Take a fork and shred it in the pot. Use it for chicken salad, chicken pot pie, soup....whatever.
Mine was for chicken and black bean enchiladas.
While we are on the subject of chicken, this is a helpful post about the price of bone in chicken vs. boneless. I always think I'm getting a better deal with bone in, but I've never accounted for the bone. What about you?
