Take two eggs. Break them into a bowl. Use a fork or something to whisk them up a bit so the yolk is mixed with the albumen.
Take two slices of bread and dunk them in the egg. Make sure to get both sides of both slices completely covered and do your best to soak up all the egg. Depending on the size of the eggs and slices of bread there may be a little bit left over.
Melt some butter in a frying pan. Put the slices of bread in the frying pan and tip the remaining egg on top of them.
While the bread is frying, slice some cheese and salami.
Once the bread is cooked to your satisfaction on one side, turn it over and put the sliced cheese and salami on top of one slice.
Once the other side of the bread is done, flip the second slice onto the first. The cheese should now be nicely melted. If not, leave it a little longer.
Once the eggy-bread is cooked and the cheese is melted, eat the sandwich.
