Creating baked dumplings is simple if you follow these easy steps:

1. Prepare the Dough: In a bowl, combine the flour and salt. Gradually add water and oil until a dough forms. Knead for about 5 minutes until smooth. Cover and let rest for 15 minutes.
2. Prepare the Filling: In another bowl, mix the shredded chicken, chopped vegetables, garlic powder, onion powder, and soy sauce (if using). Ensure everything is well combined.
3. Roll Out the Dough: Divide the dough into small balls (about the size of a golf ball). Roll each ball into a flat circle, about 4 inches in diameter.
4. Fill the Dumplings: Place a spoonful of the filling in the center of each dough circle. Be careful not to overfill.
5. Seal the Dumplings: Fold the dough over the filling to create a half-moon shape. Press the edges together to seal, and crimp with a fork for extra security.
6. Prepare for Baking: Preheat your oven to 375°F (190°C). Arrange the sealed dumplings on a baking sheet lined with parchment paper.
7. Egg Wash: Brush the tops of the dumplings with the beaten egg for a golden finish.
8. Bake: Place the baking sheet in the oven and bake for 25-30 minutes or until the dumplings are golden brown.
9. Cool and Serve: Remove from the oven and allow to cool slightly before serving.
