Add celery, bell pepper, onion, and garlic to the drippings in the pan. Cook over medium-high heat, just until the vegetables soften, about 3-4 minutes. Add the tomatoes with their juices, chili sauce, Worcestershire sauce, bay leaf, salt, pepper, oregano, thyme, and hot sauce. Reduce the heat to low; simmer until thick, stirring occasionally, about 7 minutes. Add the chicken back to the pan along with any accumulated juices on the plate and cook until the chicken is no longer pink, about 3-4 more minutes.
