In a large bowl, stir together the sausage mixture, cornbread, cubed bread or biscuits, broth, eggs, parsley, salt, and pepper. You can add a little bit of extra broth, if necessary, so that the mixture is very moist. Remember, the cornbread and biscuits will absorb the liquid and it will continue to dry out in the oven as well. Transfer the stuffing mixture to the prepared baking dish.
