Whats your favorite 5 min snack?

I often dont have much time to prepare meals for myself at home or at work. I would like to know people's favorite 5 minute snacks that can be made from items most people have. For example, My girlfriend taught me how to make cheese toast: Butter one side of a piece of bread, place it butter side up in the oven with it set to "Broil". When browned, flip and place pre-sliced cheese on non-buttered side. When the cheese is melted, take it out and enjoy. Even when it is browned, its still quite soft and delicious.
