Slice the top quarter of the tomato off. Reserve for later.
Use a paring knife to loosen the interior of the tomato.
Use a large spoon to scoop out the guts of the tomato.
Oil a baking dish with a drizzle of oil.
Place the caps of the tomatoes cut-side down in the oil dish. Stand the tomato cups on the lids.
Place 1 tablespoon of green onions in each cup, followed with the mozzarella cheese.
Crack an egg into each cup. Top with a pinch of salt and pepper.
Pile 2 tablespoons of shredded cheddar cheese on each egg.
Bake for 20-25 minutes depending on how done you like your eggs. Serve warm.
Notes
For a punchier version try adding a tablespoon of pesto or substituting a more robust cheese for the mozzarella. This recipe was inspired by viele Rezepte's recipe.
