The meat is cut into lengthwise thin strips. Lightly season with salt and season. Beat off. On a baking sheet put an inverted iron or glass bowl, grease it with vegetable oil.Starting from the bottom, lay the strips of meat, alternating between chicken and pork. The meat should be laid more tightly, because during baking it is squeezed. Grease the "ready" plate with vegetable oil, sprinkle with black pepper and put in a preheated 180-190 degree oven for 10-15 minutes.Allow to cool to room temperature. A bowl with baked meat gently turn on a dish and carefully remove it from the meat.
If you do not want to spend time on making a plate, you can simply fry the meat in a pan.
