Green Bean Quiche with Parmesan

For the dough, pour the flour on the work surface, mix with salt and make a well in the center. Cut the cold butter into small pieces and distribute around the flour. Beat the egg in the center and process all the ingredients with a pastry knife until crumbly, then quickly knead into a smooth dough by hand. Form into a ball, wrap in plastic wrap and refrigerate for about 30 minutes.

Preheat the oven to 200°C (approximately 400°F). For the filling, rinse and trim the green beans and blanch for about 6 minutes in boiling salted water. Rinse in cold water and drain. Then cut into 3 cm (approximately 1 inch) pieces. Cut the mozzarella into cubes. Cut the ham and the drained tomatoes into thin strips. Roll out the dough on a floured surface and line a buttered tart pan with it. Spread the green beans, tomatoes, ham and mozzarella over the dough.
