Return the pan to the heat and add the remaining oil. Add the rice to the pan and use a spoon to break up any clumps. Season with salt and pepper and stir-fry the rice to coat evenly with oil. Stop stirring, and then let the rice cook undisturbed until its gets slightly crispy, about 2 minutes. Stir the rice again, breaking up any new clumps. Add the scallion greens. Transfer to the bowl. Stir all the ingredients together with the rice, taste and adjust the seasoning with salt and pepper, if necessary. Serve.
