Breakfast is prepared quickly, and it is better to prepare the food in advance. The ingredients are listed for one serving, but I have two options for serving you and this is all in duplicate. You can vary the filling as you like - add herbs, finely chopped or dried tomatoes, sweet peppers, mix cottage cheese with cheese, etc., but hard cheese must be mandatory. I don't buy sausage, I found leftover pork in the refrigerator, a couple of slices of roll from the knuckle and a piece of cheese lying around...
