Preheat oven to 350 degrees.

In a 9" Pyrex Pie dish, with a spatula or butter knife, spread the cream cheese evenly across the bottom of the glass dish.

Then, layer the spaghetti sauce on top of the cream cheese.

Sprinkle the mozzarella cheese evenly across top.

Bake until the cheese on top is melted a just slightly browned.

Allow to cool for a few minutes or you will burn the roof of your mouth!
