Directions

1. Heat a deep skillet or a medium soup pot over medium-high heat. Add 2 tablespoons EVOO and the chicken. Season it with coarse salt and pepper and red pepper flakes.
2. While the chicken cooks, chop up the veggies.
3. When the chicken is evenly and lightly browned all over, 3 or 4 minutes, remove it to a plate and reserve.
4. Add another tablespoon of extra-virgin olive oil. Add the potatoes to the pan. Cook a couple of minutes, then add in the mushrooms, celery, and onion and cook another couple of minutes.
5. Add in the peppers and garlic and cook another 1 to 2 minutes.
6. Season the vegetables with salt and pepper.
7. Add chicken back to the pan. Toss it with the vegetables.
8. Add red wine to the pan and deglaze it, picking up drippings. Add tomatoes and stock to the stoup and stir to combine.
9. Stir in rosemary and reduce heat to low.
10. Cover and cook 8 to 10 minutes.
11. Turn off stoup and ladle into shallow bowls. Top with basil (for a sweet finish and balance to the spice in the soup) or arugula (for a peppery finish) or with spinach (for a woodsy finish).
12. At the table, pass grated cheese for sprinkling on top of the stoup and bread for mopping up the bowl.
