Place the chicken breasts in the base of the slow cooker and sprinkle with salt and pepper.
Add the vinegar to the base of the slow cooker.
Pour the Caesar salad dressing over the top of the chicken. If your slow cooker “runs hot” and tends to overcook, add 1/4 cup of water or chicken stock.
Set on low and cook for 8 hours. Once cooked, shred the chicken into the Caesar dressing. Assemble shredded chicken onto slider buns with a pinch of shredded lettuce and shredded Parmesan cheese on each slider.
Prepare veggies.
Serve Slow Cooker Caesar Chicken Sliders with veggies.
