Add 2 tbsp of oil to a medium sized skillet, add the diced chicken, onion powder, garlic powder, red pepper flakes and brown sugar. Stir to coat everything and cook on a medium to high heat until fully cooked and browned, about 10 minutes.
Take chicken out and set aside. Add the remaining 1 tbsp of oil to the same pan and add the cooked rice. Break up the chunks and make a circle in the middle of the rice, add the eggs and scramble them up instantly. Cook and scramble the eggs until fully cooked.
Start stirring the eggs together with the rice. Add the Japanese bbq sauce to the rice and stir until it’s all coated. Add the chicken back into the pan to heat up and top with sesame seeds. Serve and enjoy! Top with scallions! (Optional)
