In a large mixing bowl, combine the flour, baking powder, a pinch of salt, and a generous amount of Za’atar. Stir them together until well mixed.

Pour in the olive oil. Using your hands, "rub" or crumble the oil into the flour mixture until it is evenly distributed and the texture resembles coarse sand.

Create a well in the center of the mixture and pour in the water. Start mixing and kneading the dough by hand until it begins to come together.

Add the finely chopped black olives to the dough. Knead the dough thoroughly for about 5 minutes until it is smooth, soft, and no longer sticking to your hands.

Shape the dough into a ball, place it in a bowl, and let it rest for approximately 20 minutes.

Preheat your oven to 190°C (375°F).

Place the rested dough between two sheets of parchment paper (baking paper).

Use a rolling pin to flatten it into a thin, even rectangle.

Trim the uneven edges to make a clean shape.

Cut the dough into long, thin strips (breadstick style).

Alternative: You can also prick the dough with a fork and use a small circular cutter (or a coffee cup) to make round crackers.

Place the strips on a baking tray lined with parchment paper. Bake in the preheated oven for about 15 minutes or until they are golden and crispy.

Let them cool slightly to reach maximum crunchiness. Enjoy your homemade Lebanese-flavored Italian grissini!
