This sounds like a recipe request!

-put a hole in your slice of bread
-butter both sides and set the pan on medium low heat
-toast the buttered bread in the pan and season it with salt (I toast both sides because the egg cooks pretty fast.)
-put a little tab of butter into the pan in the center of the hole
-crack an egg into the hole.
-little bit of salt on the egg and wait until the whites are almost set; a little bit of cooking spray on the egg if you’re unsure about the non-stickness of your pan
-flip and wait until you achieve your perfect yolk
-plate and add ground pepper or whatever you desire

I honed my technique during COVID quarantine days.

An alternative:
-toast a slice of bread in a pan with butter and salt
-soft boil an egg
-serve the egg over the toast or use an egg cup and dip slivers of the toast into the egg
