Heat the oven to 375°F. Stir the soup and cream cheese in a medium bowl until the mixture is well mixed. Stir in the mozzarella cheese. Spread the mixture in a 1 1/2-quart shallow baking dish.
Bake for 30 minutes or until the mixture is hot and bubbling.
Serve with the bread for dipping.
Helper: To soften the cream cheese, remove it from the wrapper. On a microwave-safe plate, microwave on HIGH for 15 seconds.
