For the dough all ingredients should be at room temperature. In a large bowl break eggs, add salt and sugar, vegetable oil and yogurt, add dry yeast and mix everything carefully. Gradually introduce the flour, the dough not to score, it should be fairly soft and elastic. Knead for at least 10-15 minutes. I kneaded by hand, if you are a happy owner of a bread machine, can entrust this operation to his assistant. Put the dough back in the bowl, cover with cling film and leave to rise in a warm place.

While the batter "walks", one can prepare the filling. Cut onion into cubes, carrots three on a coarse grater. Young zucchini peel, cut into small cubes. Garlic finely chop, chop the sorrel.

Heat the pan with oil, arrange the onion. Once it becomes soft and transparent, add the carrots and fry, stirring, until soft. The meat I had prepared beef and pork. You can choose chicken or Turkey, and lamb. The ground beef and sliced zucchini spread in the pan at the same time, continue roasting on medium heat, add chili pepper, black and fragrant, sprinkle with salt.

Apple can not be cleaned, if you peel it thin enough. Grate it on a grater. When the meat cooked through and the juice in the pan becomes transparent, add the Apple and tomato paste, stir. Stew for 5 minutes under the lid.

Then add the chopped sorrel and garlic, quickly stir, cover and turn off the fire.

Abenaim the dough, divide into 6-8 balls. I got 6 pieces. Each roll out into a rectangle approximately 20 x 15 cm, thickness 0.5-1 cm. Spread warm filling along.

Forming a "boat" by wrapping the long edges on the filling, leaving the middle free. The ends of the connected pumps and a little drawn.

Put boats on the prepared baking sheet. I have a baking sheet fitted with a special pad, so the lubrication oil is not necessary. Leave the product for proofing in a warm place, covered with film. I set the silicone Mat on which you kneaded the dough. When pumps will increase markedly in volume, grease the dough with egg. Pour in the filling and 1 tbsp water. You can sprinkle the stuffing with grated cheese. Put in oven heated to 180 degrees. Baking time - 15-20 minutes, focus on your oven.
