Cut/chop the each Pastırma (pastrami) slices into 3 to 4 pieces evenly.
In a separate bowl, mix the egg, milk, black pepper, salt and vegetable oil.
Cut the phyllo (filo) sheets in triangle shape evenly and stack on top of each other.
Lay two triangle shape of phyllo (filo) sheets on top of one another and spread a tbsp of (egg, milk, vegetable oil, black pepper and salt) mix with food brush. (We are using 2 sheets on top because phyllo sheets are very thin and it may not hold the filling).
And then put 3 tbsp of filling on it and then roll smoothly. Continue until the all phyllo sheets and filling finish.
Grease baking dish and place the rolls in it. And then brush the top of the each roll with egg yolk and then garnish them with sesame seeds.
Bake the pastries in the pre-heated oven at 200 C (390 F) for about 30 minutes or until they have golden color.
