Ham Sticks

Preparation:

Preparation: The ingredients are for 12 sticks. Clean the mushrooms: remove the earth and dry the caps with a damp cloth. With a small knife, also remove the earthy base of the stems. Cut them into cubes, discarding any bruised parts. Put the oil in a pan and sauté the chopped half onion. Before it browns, pour the mushrooms into the pan, add salt and cook over high heat for about 10 minutes, stirring occasionally. Add the diced ham, the parsley and taste for salt. Turn off the heat and add the two cheeses. Let these two ingredients for the filling cool down before preparing the rolls. Roll out the dough on a floured surface into a very thin sheet and cut out 12 squares of about 12 cm per side. Place a spoonful of filling at one end, fold the side flaps inside, so that the filling does not come out, and roll them up. Line up the rolls on a baking tray lined with baking paper and brush them with the egg yolk mixed with a spoonful of water. Bake in the preheated oven at 180 degrees until they are golden brown. Take them out of the oven and serve them warm or at room temperature.
