Knead the unleavened dough. Combine water with salt and gradually add flour, kneading an elastic, not too tough dough. It should not stick to your hands or the table. Cover the dough with a towel and leave for 15 minutes.
While the dough is resting, prepare the filling. In a deep bowl, mix the greens, cottage cheese and grated cheese. Salt, pepper and mix thoroughly.
Make kutabs. Divide the dough into several small pieces. Roll each piece into a sausage and cut into small pieces. Sprinkle flour so that the dough does not stick to the table, roll each piece thinly, forming a circle. Put a thin layer of filling on half of the circle and carefully seal the edges. Place the kutabs on a dry, well-heated frying pan without oil. Fry on medium heat on each side until golden brown. During frying, the kutabs may inflate, but after removing from the frying pan, they quickly fall and become thin and flat. Grease the finished kutabs on each side with butter and stack them on a plate.
