Prepare the Dumplings: Cook the frozen dumplings according to the package instructions, either by steaming or boiling. Once cooked, remove from the water and set aside to cool.

Make the Flatbread Dough: In a bowl, mix the flour and salt. Gradually add the warm water, mixing to form a soft dough. Knead for 5 minutes, then cover with a damp cloth and let it rest for 10 minutes.

Prepare the Filling: Once the dumplings are cooled, mash them up lightly with a fork or chop them into small pieces. In a bowl, combine the mashed dumplings with green onions, grated carrots, cooked meat (if using), soy sauce, garlic powder, and sesame oil. Stir until well combined.

Shape the Flatbreads: Divide the dough into small balls (about 6-8 balls). Roll each ball into a flat circle, about 4-5 inches in diameter.

Stuff the Flatbreads: Place a spoonful of the dumpling filling in the center of each dough circle. Fold the dough over the filling to create a half-moon shape, sealing the edges by pinching them together.

Cook the Flatbreads: Heat the olive oil in a skillet over medium heat. Once hot, place the stuffed flatbreads in the pan and cook for 3-4 minutes on each side, until golden and crispy.

Serve: Remove from the pan and sprinkle with chopped cilantro if desired. Serve warm with dipping sauce.
