Sift flour, sugar, salt, and baking powder into a bowl and mix milk and oil in another.
Combine the ingredients to form a soft dough and knead for 10 minutes until smooth.
Let the dough rise in an oiled, covered bowl in a warm place for one hour.
Divide the dough into five balls and pulse pistachios, raisins, and sugar into a coarse filling.
Preheat the grill to high and heat a heavy baking sheet on the top shelf.
Roll dough into circles, fill with the nut mixture, fold over, and pinch edges to seal.
Roll into ovals, top with almonds, grill for 2 minutes, and brush with melted butter.
