Heat a non-stick pan on medium flame and melt the butter on the pan
Toast a piece of bread in your toaster (or you can use the same pan once your eggs are done)
As butter melts, crack an egg into a tall glass and whisk with a fork until fully mixed
Add chopped scallions to this egg mixture and continue to whisk
Pour the egg mixture into the pan and use a spatula to slowly move the mixture in a circle - making sure to stir often enough that it doesn't set, roughly 30 seconds (see notes below for a trick)
When the eggs have started to set (still a bit watery but you can see some white parts set) - turn off the flame but continue stirring the eggs with your spatula for 15 more seconds
Now remove the pan off the flame, add the goat cheese, and continue stirring
Finish with salt and fresh black pepper, and serve hot on toast
Notes
When the eggs are cooking, just move your spatula in a cross-like manner: one straight swipe vertically, followed by a horizontal swipe.
Make sure to add the goat cheese after you cook the eggs - adding them too early or to direct heat might curdle the cheese.
