Knead either with your hands or a processor until you obtain a stiff dough.
Set aside the dough, covering it with a clean kitchen towel for at least 10 minutes. Always keep dough covered with a cloth when you are not using/handling it.
Sprinkle your workspace with some flour. Make small, walnut sized balls out of the main dough and sprinkle each with flour. Spread each one out with a rolling pin to achieve a thickness about 1-2 millimetres.
Cut each sheet to small squares of 2 centimetres.
Put small amounts of filling on each suqare.
First fold one corner somewhat diagonally.

Make sure you stick the corners to each other. You can try different shapes or invent your own shape.
