Put the one toast bread upon the other

Make a curve with a spoon in the middle of the bread and smash the egg in it. Then put some salt and pepper upon it to make it more tasty.

Arround the top bread put the butter and the cheese upon it. ( if you would like to make it more interesting you could put also cheese between the two breads)

In the oven (200oC) for 8-10 minutes. You watch it..it might be ready also in 7minutes, depends on how you like the egg (stiff or melted)
