Preheat the oven to 350°F and line a large rimmed baking sheet with parchment paper, greasing it lightly.
Blend the cottage cheese, eggs, parmesan and almond flour until completely smooth.
Pour the batter onto the prepared pan and spread it into a thin rectangle about 1/8 inch thick and roughly 11 by 15 inches.
Bake for 25 to 30 minutes, until the flatbread is golden and firm to the touch. Let it cool on the pan for 10 minutes.
Cut the flatbread into triangles with a pizza cutter. Toss the pieces gently in a bowl with the olive oil, za'atar and flaky sea salt until evenly coated.
Spread the pieces in a single layer on a fresh sheet of parchment and lower the oven to 300°F.Bake for 25 to 35 minutes, flipping halfway through, until the chips are golden and crisp all the way through.
Let the chips cool completely on the pan before serving, as they get even crunchier as they cool.
