This one was my sister-in-law’s idea. At first I thought it sounded too simple but I tried it and learned simple doesn’t mean there is a lack of flavor! Quite the contrary!
In a non-stick skillet (or buttered regular skillet) fry a single egg.
Sprinkle a little salt and pepper to taste as the egg cooks.
I prefer to break the yolk so the sandwich doesn’t end up lopsided.
Presentation matters.
Flip once.
Butter one side of each slice of bread.
On the opposing side of one, stack half the cheese, the egg, and several slices of avocado followed by the rest of the cheese and the other piece of bread.
