How to make
Break the egg into the mince. Cut the pickles and mushrooms. Add the corn and spices.
Knead and form a roll, using foil to help you roll it up.
Put it in an oiled oven dish in a preheated oven. Shortly before it's ready, arrange round slices of tomatoes and sprinkle generously with cheese.
Finish baking until the cheese melts. Cut it into slices and serve with a garnish or salad.
