Let the dough sheets rest in the pack at room temperature for 15-20 minutes. In the meantime, grate Gouda coarsely for the cheese-ham filling. For the avocado filling, cut the avocado in half, remove the core and remove the flesh from the skin. Puree cream cheese, avocado and lemon juice with a hand blender. Season to taste with salt and pepper.
Spread a slightly moistened kitchen towel on a work surface, place a dry cloth on top. Unroll the dough sheets, cut them in half crosswise and lay them on the prepared cloths. Cover with a kitchen towel.
Cover half of the pastry sheets with ham one after the other and sprinkle with Gouda. Spread the other half of the pastry sheets with avocado cream, leaving about 4 cm free all around. Whip the edges of the short sides over the filling and roll up the pastry pieces tightly from one long side.
Gradually heat the oil in a large pan and fry the rolls in it in portions for about 4 minutes. Arrange the peace pipes. Taste hot and cold.
