In the video, a person is seen preparing a taco. They start by placing a tortilla on a flat surface. Next, they add a layer of ground meat on top of the tortilla. Then, they spread a layer of sour cream on top of the meat. The person uses a spoon to spread the sour cream evenly over the meat. Finally, they add a slice of cheese on top of the sour cream. The cheese is melted and covers the entire taco. The person then rolls up the taco and places it on a plate. The taco appears to be ready to eat.
