In a big bowl put warm milk, sugar and yeast.Keep undisturbed for 10 minutes. It will start to bubble. Add egg,salt and oil.Mix everything well and add flour. Knead to a nice smooth,elastic dough.
Oil a bowl and coat the dough ball well. Cover with a wet towel.Let the dough rest for up-to 1 hour until it double in sizes.
Mean while heat a pan. Add butter/oil. Add minced garlic. Once it is aromatic,add chopped onion. Fry till onion is golden brown.
Add minced lamb. Saute in high heat for 5-6 minutes. The lamb will start changing colour. Reduce flame add all dry spices. Let it cook till lamb is done.
Add tomatoes,and chopped red bell pepper. Let it cook for 2-3 more minutes. Stir in between.Switch off the gas.
Add chopped mint,lemon juice and give everything a good mix.Keep aside and let it cool.
Pre-heat oven to 200 degree Celsius.
Punch down the dough and release all trapped gas. Take out dough on a lightly floured surface. Divide into two pieces.
Take one part, roll dough to a oval shape. Then transfer the oval shaped dough to a lined baking sheet. Using hand stretch the dough a little more. It should turn to an oval shape. Dust top with some cornflour.
Spread half of the cooled mixture on the shaped dough. Spread half of grated cheese on top. I have sprinkled some fresh cottage cheese in one and some sliced mushroom on another pide.
Fold the side,bring together the end and pinch together. Shape the dough like boat. Refer this step by step pictures on how to shape.
Lightly beat one egg. Using a pastry dough brush the edges of shaped dough. Pour couple of spoon of egg above the filling. Sprinkle sesame seed on the edges.
Bake pide for 25- 30 minutes or until it looks golden brown.
Once done let it rest for 5 minutes,then sprinkle some zaatar on top. Slice and serve warm.
