I used the following:
Thin sliced smoked ham
First melt some butter. Then put the bacon in. Let it curl and turn it over. Then breake the eggs and lay the cheese over the eggs. Then 1 slice of smoked ham. Gives a nice salty taste. Put the lid on the pan and wait for about 4min. This is on low heat.
After 4min its finished. Put some toast under it or just plain white bread.
