Preheat oven to 400F.

Place tomato slices on a parchment lined baking sheet.

Top each tomato with a layer or parmesan and then a layer or mozzarella.

Sprinkle the chopped basil on top of each tomato.

Drizzle lightly with olive oil.

Bake for 8-10 minutes or until cheese is melted and bubbly.

Turn off oven and broil for 2-3 minutes to brown the cheese.

Serve immediately. Enjoy!
