For the dough:
Pour the flour into a bowl, add the egg, oil, and water.
Knead to obtain a smooth dough.
Roll out the dough on a floured surface and stretch it slowly to obtain a very thin dough. Let it rest for 30 minutes in the refrigerator.
Roll out the dough again on a floured surface and cut into squares.
For the filling: Slice the onions into thin rings and the bell pepper into strips.
Heat the peanut oil in a pan and cook the chicken. Add the vegetables and cook everything.
Pour in the soy sauce and spices. Mix. Set aside off the heat.
Distribute the filling on the dough squares and close them.
Cook in a deep fryer or in a pan with oil.
