We stir the cooked rice and minced pork in a bowl, laying evenly into the bake form on top of the cauliflower. Finish the layers with the other half of the cauliflower on the rice & minced pork. Cover the whole with soured cream, push into a 180C° preheated oven for 15 minutes. After the quarter of hour, take out from the oven, spread some grated cheese on top, and place back into the oven till nice brown and crisp.
