For a closed Esfirra, follow the instructions for the dough and filling. Then flatten the dough into a small circle and add the filling to it. Pull up three sides of the disc and pinch together over the filling. Ensure the filling is completely enclosed. You can make Esfirra with lamb, ground beef, chicken or even with just cheese. If you want a vegetarian version, used cooked vegetables like potatoes, carrots and peas.
