Sprinkle butter all over a phyllo sheet. Place it on the bottom of the pan with sides hanging out. Butter another and place on top of first phyllo in a cross way. Repeat with two more buttered phyllo sheets using the same method.
Add a layer of kasseri cheese. Add a layer of pastourma. Add a layer of tomato slices.
Sprinkle a pinch of cumin all over tomatoes. Add the remaining slices of kasseri. Cover with 4 buttered phyllo using the criss-cross method.
Bring in the excess phyllo and roll it in to create a border. You can trim it a little if you need to before rolling it in.
Lightly butter the top and score it. Sprinkle black sesame seeds all over the top. You can also use poppy seeds, regular sesame seeds, or nothing at all.
Bake until top is a light golden brown (about 50 min depending on your oven)
Keep your phyllo sheets covered with a damp kitchen towel while you are working. Once you put them in the pan, make sure they are buttered all over the sides. You can spray very lightly water on the sides to keep them moist.Nutritional Info – Please keep in mind that the nutritional information provided is only an estimate and can vary based on products used.
