In the video, we see a close-up of a pan on a stove. The pan has some oil in it, and we can see bits of food that have been cooked. Then, a person adds chopped onions and celery to the pan and starts stirring them with a wooden spoon. The onions and celery are being sautéed, and we can see them cooking in the oil. The person continues to stir the vegetables until they are evenly cooked.
