Place corn bread and bread slices in a food processor. Pulse until they turn into a crumbly mixture. Transfer mixture to a large bowl. Season with sage, thyme, poultry seasoning, salt, and pepper. Mix in chopped parsley, cooked vegetables, and sausage with drippings. Stir in eggs and chicken stock. This mixture should be a bit mushy. Transfer to a greased 9×13 inch pan.
