To test a slightly heated yogurt (can sour milk) to warm. Add the yeast and sugar.

Stir and add the egg and salt.

Add the sifted flour. Flour enough so that the dough has turned soft, even slightly sticky to the hands.

Add the vegetable oil (very little need to leave for the formation of a cake, simply grease the baking sheet and moisten your hands) and knead the dough for 5 minutes. Thanks to oil, the dough will become more elastic and stops sticking. Leave in a warm place, covered with a towel, to approach.

Meanwhile, for the filling, cut the pork (you can use any meat or chicken). I got a rather large straws. Fry meat in small amount of vegetable oil.

Add onion, cut into strips. Fry together.

To fried meat with onions add the chopped fairly large pieces, mushrooms. I have mushrooms was average size, I just cut them into 4 or 6 pieces. Nothing fry!!!

And add the greens, chopped finely, salt to taste, mustard. You can add favorite spices, but I only had mustard, it gives a fairly bright taste (who doesn't love mustard, it's better just not to put, as it clearly does in a cake). I just added more black pepper.

Hands and protiven grease with vegetable oil. Formed from the coming up of the test pellet, a fairly large (just use all the dough, the size of the pan). Put in the middle of the flatbread toppings, slide.

The edges gather to the center. The dough is quite soft, maybe a little off-rasplava tsya, but it's not terrible, most importantly, to gather it in the center. I left the holes is not accidental. In these holes initially, before baking, I poured 0.5 cups of water (cold, boiled. If you have broth, it's even better), evenly distributing it over the holes. And in the middle of baking he poured much more water. Bake pie in a preheated 190 degree oven until tender. Availability (if different doubt) can be defined as... If the cake easily detaches from the pan, it means it is ready. It is, of course, Bouncing will not, but by lifting it with a spatula, you will see that the bottom is cooked.

Served warm or cold.
