Place the flour and salt in the food processor.
Add the butter, egg and water. Process for about one minute or until a dough forms. Form a ball with the dough and place in the refrigerator for about 25 minutes.
Roll out the dough into a large sheet and cut out round shapes for empanadas. To assemble the empanadas, place mini marshmallows and chocolate chips on the center of the empanada discs.
