Position a rack in the lower third of your oven and preheat to 425°F / 215°C.
Divide the pizza dough into four equal portions and roll each into a 6-inch circle.
Place the dough circles on a baking sheet.
Brush each circle with ½ tsp / 2. 5 ml (0.2 fl oz) of olive oil.
Sprinkle each flatbread evenly with 1 tsp / 5 ml za'atar, ½ tsp / 2. 5 ml sesame seeds, and ¼ tsp / 1. 25 ml (0.8 fl oz) crushed cumin.
Season each with a small pinch of sea salt and black pepper.
Bake for 11 to 14 minutes, or until the edges and bottom are golden brown and crisp.
