Start by preparing your dough (if making it from scratch) and roll it out into a round shape (for a more attractive presentation).If using store-bought dough, simply unroll it.Place the dough flat on a baking sheet lined with parchment paper.Prick the base with a fork to prevent it from puffing up during baking.
Bake for 10 to 12 minutes for store-bought dough, or 15 to 20 minutes for homemade dough.Keep a close eye on it: the dough should start to turn golden but not overcook, otherwise it might crack when sliced.
Then, let it cool.
For the topping
Wash and dry your tomatoes, then cut them into thin slices.Lightly salt them and let them drain.
Prepare the base of the filling by mixing the cream cheese, chives, and finely chopped shallot (or spring onion) in a bowl.Spread the mixture over the baked and cooled tart shell, leaving a margin of about 1 centimeter around the edges.
Arrange the tomato slices on the fresh cheese.
Then add the ingredients of your choice: here, chives, pine nuts, and red onions pickles.
