See my other recipes for baking the biscuits and cornbread for the dressing.
Preheat oven to 350F
Mix all of the ingredients in a large bowl until well blended.
Place mixture in a 9x9 casserole dish. Use a spoon to spread it evenly.
Place casserole dish in oven uncovered. Bake for about 30 minutes.
Check if the dressing is done by placing a toothpick in the center. If the toothpick comes out with nothing on it, the dressing is done.
