Drizzle the chicken all over with olive oil and season with the salt and pepper. Place in a greased 6-quart crockpot in a single layer.
Top chicken with the onion, garlic, dried herbs, black beans, crushed tomatoes, and balsamic vinegar.
Cook on low for about 3 hours (or until a thermometer reads 165°F when inserted into the thickest part of the breast.)
Serve with a little sprinkling of chopped parsley and enjoy!
