Potato, Cheese, and Herb "LAPTI" Hand Pies

Warm the kefir slightly, then whisk in the egg, salt, sugar, and vegetable oil.

Add the flour and baking soda, and knead into a smooth dough. Cover with plastic wrap or a kitchen towel and let rest in a warm place for 30 minutes.

Peel the potatoes and boil them in salted water, drain, and mash until smooth.

Finely dice and sauté the onion until golden, then add it to the potatoes along with the processed cheese, finely chopped dill, salt, and pepper, and mix well.

Divide the dough into medium-sized balls, flatten each one with your fingers, place the filling in the center, and seal to form a pie.
