Heat the butter in a large skillet over medium heat.
Whisk the eggs very well then season with sea salt and freshly cracked pepper, to taste.
Pour the egg mixture into the hot large skillet. Constantly fold the egg mixture from the bottom of the pan to the top. This will keep it from overcooking and the middle section will stay soft and fluffy. Do this constantly for 1 or 2 minutes, or until the eggs are cooked to your liking.
Meanwhile, place your bread into the toaster and toast; butter the toast when finished. Slice the avocado into slices.
Layer the scrambled egg on top of the buttered toast followed by slices of avocado. Season with sea salt and freshly cracked pepper, to taste. Serve immediately. Enjoy.
