Brown one package of sausage. (That's the not quite vegetarian part. Omit it for a vegetarian recipe, and add 3tbsp of oil and a dash of salt instead.) Add 6 stalks celery, minced, 1 large white onion, minced, 2 - 3 cloves garlic, 1 bell pepper, chopped. Chip 2 or 3 carrots into the mix. Aim to get around 10 cups of raw vegetables. Sautee until the onion goes clear. if you want, add another chopped onion, and sautee a bit more.
Add 1 stick of butter, and cook over low heat until melted. Add 1 to 2 tsp of sage, thyme, gumbo file, parseley, pepper, or other herbs. Add chopped nuts if you want. Adjust to your own taste. Add your seasoned bread stuffing mix. One or two bags, whiciever works.
Stir it up, making sure to get everything damp. Lower heat to the lowest possible flame, or a "low" setting. Cover the pot and cook, stirring every 5 minutes or so. Eventually, everything will get steamed and the flavors will mix.
If the mix is too dry, add some water or broth and let it steam the stuffing.
You can also add mushrooms for some meat-like texture. Wash, cut into quarters, and add to the vegetables as they sautee.
