Preheat the oven to 200ºC and line baking trays with baking paper.
Place the ingredients in a bowl and mix well with your hands.
Roll in the pastry to get the sizes you want. Place on the trays seam side down. Put a hole or a slash in the top of each to allow the steam to escape. Brush the tops with the egg yolk mixed with a tablespoon of water.
Bake 20 mins then check if any liquid has come out of the rolls and soak it up with paper towels if there is any. Bake another 10 mins. Adjust the cooking time for the size of the rolls.
