Place chicken breast/tenderloins in the crockpot with about 2 c. water. I did 1 very Large breast and it was more than enough for 5.
after it has cooked on low 5-6 hours or more drain the water and shred the chicken and return to the crock pot. Add 1/2 C. caesar dressing. you may need more or less depending on the amount of chicken. you just want it coated but not drenched in the dressing. add 1/2 c. fresh shredded parmesan (NOT the powdery stuff you use on spaghetti!!) then return to pot and cook on high 30 min. Serve on buns with lettuce.
