Prepare the puff pastry as the base for your tarts.
For the first tart, layer sliced tomatoes on the puff pastry and spread chive and dill cream cheese on top.
For the second tart, combine marinated olives with plain cream cheese and spread this mixture over the pastry.
For the third tart, mix fresh blackberries with lemon juice, thyme, vanilla, and olive oil, then place this mixture on the pastry.
Sprinkle sumac, lemon zest, oregano, and chopped chives over the tarts for added flavor.
Bake the tarts until the pastry is golden and flaky.
