Toast bread and lightly butter. Sprinkle with just a tad of kosher salt.
Fry or poach your egg. (I fried mine with a really runny yolk)
Spread mashed avocado on buttered toast.
Squeeze lime on avocado (I know, sounds weird, but it's good)
Top with egg.
Finish off with a little cracked pepper and chopped cilantro (optional).
