Heat oil in a large Dutch oven over medium. Add onion, celery, and carrots; cook, stirring occasionally, 5 minutes. Add mushrooms and garlic; cook, stirring often, 3 minutes. Stir in stock, thyme, bay leaves, and chickpeas; bring to a simmer. Add chicken, salt, and red pepper; cover and simmer until chicken is done, about 25 minutes.
