In a mixing bowl, combine flour and salt. Add cold butter and mix until crumbly. Stir in ice water until dough forms.

Press the dough into a 9-inch pie dish and refrigerate for 30 minutes.

In a large bowl, layer sliced tomatoes, mozzarella, cheddar, basil, oregano, salt, and pepper.

In another bowl, whisk together eggs and mayonnaise. Pour over the tomato mixture and gently mix.

Preheat the oven to 375°F (190°C). Pour the filling into the prepared crust.

Bake for 45 minutes or until the filling is set and the crust is golden brown.

Let cool for 10 minutes before slicing and serving.
