For slices of toast bread, cut hard edges (crust) from all sides. And carefully roll out all the slices with a regular rolling pin.
Slice the cheese very thinly in size slices of bread, but not more. Put a piece of cheese on the bread.
You can add a thin slice of ham or even a sausage to the cheese.
Prepare a batter from an egg and your favorite spices, mixing everything together, intensively whipping with a fork.
Pour oatmeal into a separate dry bowl - they will be used instead of breadcrumbs.
Pour vegetable oil into a pan and heat. Roll each piece of cheese into a tube. So that the edges do not stick up, you should get a small roll. Dip it quickly first in the egg, then in the cereal and immediately put it in the pan.
Fry on all sides for about a minute - the top should be evenly browned and the cheese melted inside.
Serve instantly in hot form while the cheese is spreading.
