In the same pan, heat oil and add chicken (season with Cajun seasoning, salt, and pepper) and cook for about 3 minutes.
Move the chicken to one side of the pan and add the garlic, chopped onion, thyme and cook until soft and translucent.
Add all the peppers, chopped celery and combine. Sauté for about minutes and make sure you stir occasionally.
Stir, serve
Enjoy!
