To make this dish, I started by dumping a jar of marinara sauce into a large saute pan over medium heat.

Then I added some frozen Italian meatballs to the pan.

I stirred until all of the meatballs were coated in sauce.

I left the meatballs to cook, stirring occasionally, for ten minutes.

After ten minutes I reduced the heat to low.

Then I placed six slices of bread on a cutting board and spread them with garlic margarine.

I cut all of the slices of bread in half.

Then I placed the pieces of bread, margarine side down, in the bottom of a greased 9 x 13 inch baking dish.

I sprinkled some shredded mozzarella and cheddar cheese on top of the bread in the baking dish.

Then I spooned the meatballs and marinara over the cheese.

I sprinkled some more shredded mozzarella and cheddar cheese on top of the meatballs.
