Incorporate the diced red bell pepper and shredded carrots, cooking for 2-3 minutes.
Add the cold cooked rice, breaking up any clumps with a spatula.
Pour in the soy sauce and Bang Bang sauce, stirring to coat everything evenly.
Season with salt and pepper, adjusting flavors as necessary, and cook for an additional 3-5 minutes.
Stir in the chopped green onions just before serving.
