In a large skillet, heat up the oil, over medium heat.
Add the ground beef, celery, pepper, garlic, and onion and cook, breaking up the beef while stirring, until the ground beef is cooked through and the vegetables are tender.
Add the parsley and creole seasoning, starting on the low end with 1 tbsp and tasting before leaving it or increasing the amount as desired, stirring to combine.
Then stir in the cooked rice, and saute for 5 minutes, or until heated through, over medium heat.
Serve immediately, and enjoy!
