In a large stockpot sauté onion, garlic and celery in oil for about 7 minutes until the veggies turn a bit brown.
Add the tamari and continue to cook for an additional 2 minutes.
Add black beans and tomatoes with juice, corn, spices, TVP and water. Stir well, and bring to a boil.
Reduce heat to low, cover and cook for 20 minutes.
Meanwhile, add miso to a small bowl.
Ladle a cup or so of the chili over the miso and mash and stir to dissolve. Gently add the mixture back to the stockpot.
Taste the chili for seasoning.
Serve in bowls with chopped onion or pepper, cilantro, salsa, sour cream and/or grated cheese (vegan or otherwise) on the side.
