In a bowl mix eggs, sugar, oil, vanilla extract and salt.
Then, add 400gr of the flour and start mixing with a fork until you have a homogeneous dough, with no dry flour. Then, mix in the rest 50n grams with your hands.
Weight balls 0f 30 grams each (each ball will be a cookie). Place the dough on your hands, flatten the dough out, shaping a circle with approximately 1/4" thickness.
Place your preferred jam in the center, then fold in the sides of the circle to achieve a triangular shape.
Place carefully on a baking sheet covered with parchment and bake at 180°C (350°F) for aprox. 12-15 minutes or until the bottom is light golden brown.
Let them rest for about 5 minutes on the baking sheet and transfer to a wire rack to cool completely if you really can wait lol (I couldn't!)
