The video shows a woman preparing a sandwich in a kitchen. She starts by opening a bag of lettuce and placing it on a cutting board. Then she takes out a bottle of salad dressing and pours some onto the lettuce. She then takes out two slices of bread and places them on the cutting board. She then adds slices of cheese and tomato to the bread and tops it with the lettuce. Finally, she places the sandwich into a blue lunchbox.
