Hollow out the center of each slice. Heat some oil in a heavy frying pan and add the bread.
Add an egg to the center of each slice of bread. Do this slowly so the egg begins to set and doesn't flow out from underneath the bread. Cook until the bottom of the egg is well set.
Flip once and allow to cook for a few minutes longer.
Top with mozzarella cheese and lid the pan for a few minutes until the cheese melts.
Voila! I sometimes add Mrs. Dash Garlic & Herb to the top of the eggs for extra flavor.
