Boil the rice in water, but do NOT wash it beforehand. Once it is cooked well, add the butter. Put half of the cooked rice in a buttered baking dish, and on top of it, place the chopped smoked chicken, round tomato slices, black pepper, cumin.
Top with the rest of the rice and shred feta cheese and cheese on it. Bake to reddening. PS: the chicken meat can be substituted with fish.
