The cooking for pineapple fried rice is very quick (as shown in the video in real time), so you might consider measuring out all ingredients, chopping the vegetables, cooking off the protein, and combining the seasonings so that everything is ready to be thrown into the wok. If you want to make the fried rice in advance you absolutely can, and it reheats well, but do not add the cashews, tomatoes and green onions. Toss those in after reheating, right before serving.
