Preheat the oven to 375°F (190°C). Place the pre-made pie crust in the pie dish and set aside.

In a mixing bowl, combine the sliced tomatoes, mozzarella cheese, cheddar cheese, basil, thyme, salt, and pepper.

In another bowl, whisk together the eggs and heavy cream until well combined.

Pour the egg mixture over the tomato mixture and stir gently to combine.

Pour the filling into the prepared pie crust and spread evenly.

Bake in the preheated oven for 40-45 minutes, or until the filling is set and the top is golden brown.

Remove from the oven and let cool for 10 minutes before slicing and serving.
