In a dutch oven, brown seitan in olive oil over medium heat. Season with salt & pepper to taste. Remove browned seitan from the dutch oven and set aside.
Next, saute the onions, celery and carrots over medium heat in the remaining olive oil using the same the dutch oven that you used to brown the seitan. Cook until softened.
Mix in all remaining ingredients except for the seitan. Season with salt & pepper to taste. Bring to a boil, and then reduce the heat to simmer for 45 minutes.
Add the seitan and simmer for another 15 minutes or until the potatoes are fork tender.
Dinner's Ready! Serve your Provencal Stew with a slice of warm, crusty French baguette.
