Make the dough: In a mixing bowl whisk flour and salt, add warm water and 1 tbsp olive oil, then knead 3–4 minutes until smooth; cover and rest 10 minutes while prepping the filling.
Prep vegetables: Finely dice the onion, mince the garlic, chop the mushrooms very small, and finely chop spinach, dill, and parsley.
Cook aromatics: Heat 1 tbsp olive oil in a large pan over medium, add onion with a pinch of salt, and sauté 3–4 minutes until translucent.
Add mushrooms and garlic: Stir in mushrooms and garlic, cook 5–6 minutes until most moisture evaporates and edges start to brown.
Season and finish filling: Fold in spinach, dill, parsley, coriander, cumin, paprika, pepper, and chili; cook 1–2 minutes just to wilt, adjust salt, then cool slightly.
Portion the dough: Divide dough into 6 equal balls (~60 g each) for two qutab per portion.
Roll and fill: On a lightly floured surface, roll each ball to a thin 18–20 cm circle, spread a sixth of the filling on half, leaving a 1 cm edge, then fold over and crimp firmly.
Pan‑cook: Heat a dry pan over medium, brush the top of a qutab lightly with olive oil, place oiled‑side down, brush the top, and cook 1–2 minutes per side until golden spots appear and the flatbread blisters.
Make the sauce: Whisk vegan yoghurt with sumac, lemon zest and juice, and a pinch of salt until smooth.
Keep warm and serve: Hold cooked qutab under a clean towel while finishing the batch, then serve hot with the tangy yoghurt.
