In the meantime, prepare your Kiymali Pide filling by heating 1 tbsp of olive oil in a large non-stick pan.
Stir in the onions and peppers and sauté for 2-3 minutes over medium heat, until they soften.
Add the tomatoes and sauté for another 2 minutes. Pour in the lemon juice and season with salt and ground black pepper. Add cumin, sumac, and paprika. Stir to combine then turn off the heat.
Place the ground meat in a bowl and combine the cooked vegetables with the ground meat, mix well.
Place the risen dough on a lightly floured surface. Knead the dough for a minute then divide the dough into two pieces and roll into two balls.
On a lightly floured surface, roll the dough balls into 2 oval shapes of 20 cm x 40 cm with ½ cm thickness.
Line a large baking sheet with parchment paper and place the 2 oval flat dough pieces on the tray.
Spread the filling evenly over the 2 flat breads, leaving 2 cm at the edges as a border with no filling.
Fold in the sides to act as crust to keep the filling intact. Squeeze the oval dough at each end to make it pointy.
Beat an egg in a small bowl and mix it with a few drips of olive oil. Brush the edges of dough with the egg mixture.
Bake for 25 - 30 minutes, until the Turkish Pide are golden brown and crispy at the edges.
Once cool, cut into slices and serve.
