In a food processor blend your flour, salt, and sliced butter (or use a bowl and a pastry cutter) until it becomes like a coarse meal.
Add the egg and process in the food processor until it becomes a soft dough. Roll out, and place in a greased tart tin. You may have extra dough (which you can save and freeze). Place the tin in the freezer for 20 minutes.
Par cook your crust (line it with parchment and pie weights - or uncooked rice) and cook at 350°F (175°C) for 8 minutes, until lightly golden. Remove from the oven and cool while you prepare your custard. You can leave the oven on.
For the Quiche:
In a medium-sized bowl, mix your heavy cream, yogurt, and sour cream. Add your three eggs, and blend well. Add your za'atar, fresh parsley, salt, and pepper, and stir to combine.
Place your tomatoes into the crust, then pour the egg mixture over the top, almost to the top of the crust. Sprinkle the top with more za'atar if desired.
Bake for 30-35 minutes until lightly golden on top and just set. Cool on a wire rack at room temperature and serve.
