In this part, we need to heat up on low heat a large pan with olive oil, add the chopped onion. Sauté for 10 minutes till you see it starts getting translucent then add the garlic, spices and keep it on the low heat for a few more minutes.
Now chop the aubergine and add it to the pan and stir for a minute. Chop the tomatoes and add them to the pan and mix them.
Add a cover to the pan and continue stirring from time to time in the next 15 minutes.
Then chop the mint and with the sumac add them to the pan and stir again to mix with the rest.
Preheat the oven to 200C. Take the dough and divide it into 4 pieces and then roll them into long oval shapes.
At each end of the dough, you can make a pinch.
Now using a wooden spoon you can transfer the mixture from the pan onto the central part of each dough piece, but make sure you leave a space around the edge.
Into a baking dish add a little oil and then fold the edges over the filling a little and put it in the oven.
You'll notice in about 12-15mins the crust is getting golden and it is cooked.
Turn off the over, take the baking dish out and before serving add on top freshly chopped fresh mint, pistachio and pomegranate seeds.
