Turn on the stove on medium heat and add olive oil to a large pan or a wok on it.
Add onions to oil and a pinch of kosher salt. Mix well and cook until onions are soft, stirring often.
Now, increase the stove flame to medium-high heat. Add rice, hot sauce, tamari, and Worcestershire sauce.
Add the leftover fried chicken and toss to combine everything well.
Spread evenly into the pan and let them cook for 30 to 60 seconds. Toss 2-3 times.
Taste the seasoning and add more hot sauce or Worcestershire sauce if you desire.
Serve the leftover fried chicken and rice with sliced green onions. Enjoy!
